Interwoven Reality and Illusion Urban Impression Art Poster

Generate a vertical city poster in the style of “Blending Void and Reality” with the theme [City Title].

Core concept:
The entire image should present a natural left-to-right transition from “high-fidelity realistic watercolor → blended watercolor and reality → high-definition real cityscape.” It should not look like two separate images stitched together left and right, but rather like the same city in the same spatial environment gradually awakening from watercolor imagination into the real world.

Composition:
1. Vertical 4:5 composition, generated as a single standalone image, not a four-panel layout and not a collage.
2. Full-bleed image with no large blank paper background.
3. The left third should be a realistic watercolor cityscape with complete buildings, roads, water, trees, bridges, urban spatial structure, and depth.
4. The watercolor area on the left must not be just faint pigment washes or blank background; it should look like a fully and carefully painted real city in watercolor.
5. The middle area should be a natural blending zone where buildings, sky, water, trees, bridges, and roads all participate in the material transition.
6. The transition must be continuous, soft, and layered, not a hard cut and not a crude splice between two images.
7. The right third should be a high-definition realistic city view with natural light, rich detail, and a strong sense of reality.
8. The overall feeling should be that the city is slowly waking up from a painting, moving from imagination into reality.

Visual style:
1. The left watercolor side should be realistic, richly detailed, and structurally clear, while preserving paper texture, brushwork, watercolor bloom, and hand-painted quality.
2. The right realistic side should be crisp, transparent, modern, and photographic.
3. The overall mood should be bright, clean, refined, restrained, artistic, and modern.
4. The palette should focus on sky blue, urban gray, vegetation green, and water blue, with soft warm highlights to enhance layering.
5. Avoid childish cartoon aesthetics, traditional tourism-poster styling, and overly retro yellowed tones.

Text requirements:
1. Keep text minimal and overlay it directly on the image without complex layout.
2. Only keep the main title: [City Title].
3. Use the subtitle: “From Watercolor to Reality”.
4. The font should be simple, elegant, and restrained, without overpowering the image.
5. Do not include large amounts of explanatory small text or excessive information.

City content:
Accurately depict the most recognizable cityscape elements of [City Title], including [Core Landmark] and the distinctive features of [River/Harbor/Mountain/Road/Bridge]. The city should be highly recognizable overall, so that viewers can roughly identify it even without reading the title.

Avoid:
Do not leave large blank areas; do not show only watercolor pigment without actual city content; do not create a hard split in the middle; do not make the left and right feel like a pasted collage; do not use wildly inaccurate landmarks; do not include garbled text; do not overdecorate; do not use low resolution; do not make the image look dirty or cluttered.
