City Poster Watercolor to Real Skyline

Scene:
- Vertical 4:5 city poster
- The same city in one continuous space, gradually shifting from a watercolor mood into the real world
- Across the full image, create a natural left-to-right transition: highly finished realistic watercolor → blended illusion and reality → high-definition real cityscape
- Full-bleed composition
Subject:
- Theme: 【城市标题】
- The left third is a realistic watercolor cityscape
- The left side must include complete buildings, roads, water, trees, bridges, urban space, and clear depth from foreground to background
- The right third is a high-definition real cityscape
- Accurately show the most recognizable urban scenery of 【城市标题】, including 【核心地标】 and 【河流/海港/山体/道路/桥梁特征】
Important details:
- The image is not a simple side-by-side splice of two pictures; it is the same city naturally transitioning within the same space
- The center area is a natural blending zone, where buildings, sky, water, trees, bridges, and roads all take part in the material transition
- The transition is continuous, soft, and layered
- The watercolor side is realistic, richly detailed, and structurally clear, while preserving paper texture, brushwork, pigment blooms, and a hand-painted feel
- The real side is sharp, transparent, modern, and photographic
- The overall mood is bright, clean, refined, restrained, artistic, and modern urban
- Main colors are sky blue, city gray, vegetation green, and water blue, with optional soft warm light and shadow
- Use minimal text, overlaid directly on the image: keep only the main title '【城市标题】' and use '从水彩到现实' as the subtitle; typography should be simple, elegant, and restrained, without overpowering the image
