AI Generation Comparison: JiMeng vs NanoBanana

I conducted an interesting experiment: generating images using the same prompt on JiMeng and NanoBanana to see how the two AI tools differ in their presentation.First, let’s take a look at the results from JiMeng and NanoBanana. (Left is NanoBanana, right is JiMeng)Island Dream MapPrompt:

Aspect ratio 16:9. A dreamy and delicate hand-drawn map of a fantasy island archipelago, with an overall style reminiscent of Studio Ghibli's art design collection: soft watercolor base, wet and dry blending, pen and light color outlines, presented on a piece of textured, slightly curled old parchment. The overall atmosphere is warm, whimsical, and filled with adventurous romance. The theme and style of the map are presented in an isometric perspective, depicting a sea composed of multiple fantastical islands. The islands are illustrated as cute and exquisite miniature landscapes, featuring highly detailed small elements, such as: "Changfeng Island" with its white windmill cluster, "Coral Bay" with its pink coral reefs and transparent waters, "Yunwhale Cliff" with giant whale-shaped clouds floating at the cliff's edge, and "Star Lantern Port" with its glowing lighthouse and small fishing boats. The islands are connected by winding sea routes, glimmering dot patterns, and tidal textures, with a layout that is natural, organic, and not grid-bound. 🖋 Key Typography Challenges (must be hand-drawn style, extremely high requirements) All text must be in a slightly casual yet elegant handwritten style (running script/cursive), as if completed with the same pen as the illustrations. It must reflect the imperfect human touch and brush strokes. 1. Main Title (Focus): The main title "Island Dream Map" is written on a flowing hand-drawn scroll at the top, with the font flowing naturally, slightly ink-stained. 2. Slanted Fun Tags (Place Name Labels): Each island has a slightly tilted, playful handwritten label, such as: "Coral Bay", "Star Lantern Port", "Windy Cliff", "Moonshadow Village". These labels must be placed organically, not strictly horizontal or mechanically aligned. 3. Curved Text Along the Path (Super Challenge): A main shipping route "Starlight Route" runs through the entire sea area. The phrase "Starlight Route" needs to be elegantly curved along the winding route, perfectly fitting the shape of the path, which is the core testing point of this prompt. 4. Fun Annotations with Text + Icons: Small handwritten annotations scattered across the map must integrate small icons: "Sea monsters are lurking!" with a small tentacle drawn next to it, "Best stargazing spot" with a tiny glowing star next to it, "Fisherman's secret passage?" with a small crab drawn next to it, and "Deep Sea Song" written in a shell-shaped dialogue box. All annotations must naturally blend with the illustrations, rather than being overlaid text layers. 5. Hand-drawn Legend Area: In the lower right corner, draw a hand-drawn legend box (with slightly damaged edges) containing: a small anchor (representing the port), a shell (representing the shallow area), a windmill (representing the wind source), and a small whale icon (representing whale sighting points), along with corresponding handwritten annotations. 6. Red Hand-carved Seal: In the lower left corner, stamp a red seal with the character "Dream", slightly pressed over the edge of the map, with natural ink bleeding. 🎨 Aesthetic Requirements: Watercolor should be soft, transparent, and richly layered, with visible water stains, paper texture, and color bleeding at the edges. Pen lines should be lively, vivid, and have a sense of breath. The overall tone is warm but carries a hint of adventurous fantasy. The entire piece is a highly artistic hand-drawn fantasy map where text and illustrations are fully integrated. ❌ Negative Prompt Words (must not appear): Computer fonts, mechanical text, rigid horizontal lines, straight grid lines, perfect alignment, stiff layout, floating text layers, photos, realistic 3D style, minimalist geometric icons, garbled text, spelling errors, watermarks

Pyramid StructurePrompt:

Please create an infographic about pyramids. Use a real pyramid photo as the background, overlaying a blueprint-style white technical line drawing. Include outer contour lines, internal passage indications, vertical sections, floor structures, major dimension annotations, material quantities, load flow arrows, and other architectural information. The lines should have a chalk or engineering drawing hand-drawn feel, not obscuring the overall photo. Include Chinese technical annotations in the image, covering key dimensions, structural features, material information, and internal layout descriptions. In the lower right corner, draw a hand-drawn small box with the title: Pyramid Structure Infographic. The overall style is blueprint aesthetics: a real photo overlaid with white engineering line drawings, combining educational and technical feel, presented in Chinese.

Seaside Cruise ShipPrompt:

Inside a crowded seaside cruise ship, all passengers are fantastical marine creatures: colorful mermaids crowding by the deck railing, a sea dragon with golden scales leisurely walking down the aisle, an octopus passenger holding a drink with its tentacles, and a sea turtle slowly moving with luggage. Above the porthole, an electronic screen flashes blue text: "Attention passengers heading to the deep sea secret realm, next stop: Coral Bay". A warning sign at the entrance reads: "No magic or water skills allowed in the cabin". The overall scene presents a clash between the modern cruise environment and the fantastical marine world, with rich colors and humorous liveliness.

Starry Sky RailwayPrompt:

Aspect ratio 16:9, an official crossover promotional poster, masterpiece-level presentation. The visual style is high-energy, dazzling, and shining in the anime style of "Honkai: Star Rail". 🎬 Scene Setting: Four fashionable, futuristic characters pose in the night square of the interstellar station. Each holds a cup of glowing energy drink (Energy Spark), with the liquid slightly glowing in the cup. Character Composition (visually balanced, strong trend): Center character: A girl with blue hair in twin ponytails, wearing a white flight jacket, exuding confidence as the focal point of the image. To her left: An elegant woman with long blonde hair, wearing a star-patterned long coat. To her right: A red-haired young man in functional exoskeleton armor. In the distance: A silver-haired cool short-haired girl wearing semi-transparent goggles. The four are in dynamic standing poses, filled with the momentum of a "team debut". 🌌 Environment: This is the "Orbital Train Station · Star Port No. 7" located in space. The night sky is deep, with flowing nebulae. The entire scene is covered by a giant sci-fi light source: the most prominent part of the background features a huge, glowing galaxy train sign (AstralRail) in neon, arched and suspended, serving as the absolute visual anchor. Other floating advertisements themed around "Energy Spark" project bright blue-purple and pink light. The metallic platform has a reflective effect, with light dynamically reflecting on the ground and characters. ⚡ Special Effects: The image intersperses many sci-fi elements: semi-transparent small meteor fragments floating around the characters. Glowing energy vortices slowly flow in the background. The energy drink in the cup emits faint particle effects. Miniature "star trails" lightly swirl around the characters. The effects must remain full but not overwhelm the characters. 🖋 Text Elements (Key Requirements): In the upper left corner: Display two logos: the official "Starry Sky Railway" logo and the "Energy Spark" drink logo, separated by an "X". The design must be exquisite, clean, and have a metallic decorative feel. In the bottom center: A prominent large Chinese title: "Starry Sky Railway X Energy Spark: Ignite Cosmic Energy!" Font: bold, with sci-fi angles, white main body, edges with heavy blue-purple energy gradient outlines, with a slight inner glow effect. Below it: In a black rectangular box, write: "INTERSTELLAR COLLAB — LIMITED EDITION" in white sans-serif uppercase letters, with extremely clean typography. 🎨 Artistic Style: Highly detailed, clean lines, cinematic light and shadow from giant neon lights, strong color contrast, dynamic composition emphasizing team momentum and energy flow. The overall presentation is at the level of a professional high-end game official promotional image. ❌ Negative Prompt Words: Blurry, low quality, distorted human structure, deformed hands, ugly, watermarks, signatures, garbled text, letter deformation, dirty light effects, unnatural reflections

Cloud Qin Landscape MapPrompt:

Aspect ratio 16:9, a magnificent and exquisite illustrated ancient dynasty map depicting the territory of the "Yun Qin Dynasty". The overall style draws from the delicate brushwork of Song Dynasty boundary paintings and landscape scrolls, with mountains presented in rich green and blue colors, and cities and palaces depicted with meticulous detail, as if crafted by a court painter. The base material is yellowed rice paper, with natural fiber texture. Composition and Perspective: Using ancient landscape "scattered perspective", mountains, cities, and rivers are presented in multiple viewpoints within the same frame. The central hub of the dynasty, "Yun Jing", is located in the center of the image, with mountains, river networks, and passes naturally spreading around it, resembling a grand landscape scroll. Key Illustrations and Regional Scenes — As miniature narrative landscapes: • Yun Jing: Nine-layered palaces, red high platforms, golden tiled flying eaves, with strict ceremonial guards. • Cangling Pass: Soldiers training in front of the giant stone-built pass. • Qiong River: Cargo boats lined up, reflecting the green mountains on the water surface. • Hansha Ridge: An ancient altar hidden among the cliffs. • Lizhou Ancient City: Bustling markets with merchants carrying loads and musicians playing on the towers. — As map elements, characters: Civil officials, military generals, merchants, and boatmen appear as miniature detailed figures, serving both decorative purposes and naturally guiding the viewer's gaze.
