)彩风现实城市海报

Create a single vertical 9:16 poster image for the city titled "[CITY NAME]". Theme: "From Watercolor to Reality" - a seamless transformation of one continuous city scene. Core requirement: The entire image must depict the same exact city scene from the same viewpoint, with the same composition, the same skyline, the same waterfront / roads / bridges / buildings / spatial relationships. Do not create two different scenes. Do not change the camera angle from left to right. Do not replace the content across the image. It must feel like one single city scene, where only the visual language gradually changes from watercolor to photorealistic reality. Visual structure: - The left side should be a highly detailed realistic watercolor interpretation of the same city scene. - The middle should be a smooth, seamless blending transition zone. - The right side should become fully photorealistic reality. - The transition must be coherent, elegant, visually connected, and natural. - Buildings, skyline, sky, water, reflections, roads, bridges, greenery, and all key landmarks must align perfectly across the transition. Style requirements: - The watercolor side must be detailed, refined, and realistic, not loose, empty, or abstract. - The right side must look like a high-end realistic city photograph. - The middle area should show a gradual material transformation: watercolor paper texture, brushwork, and pigment wash slowly dissolve into realistic light, texture, and detail. - The whole image should feel premium, elegant, globally appealing, clean, and visually striking. Composition requirements: - Vertical 9:16 format. - Full-bleed composition, no large empty white margins. - One single poster only. Generate this image independently, not as a collage or multi-panel layout. - Keep the layout visually balanced and poster-like. Text on image: - Use English only. - Main title: "[CITY NAME]" - Small subtitle: "From Watercolor to Reality" - Minimal text only, elegant typography, not too dominant. Avoid: - No split-screen feel. - No hard cut between left and right. - No two unrelated scenes stitched together. - No extra blocks of text. - No low-detail watercolor emptiness. - No inaccurate landmark placement. - No cartoonish look.
