21:9超宽横版扬州旅游主视觉KV生成提示词

21:9 ultra-wide horizontal tourism project key visual (KV), strictly following the reference image's overall visual style, composition method, line drawing expression, scenery layout, and artistic texture, only replacing the regional elements with Yangzhou characteristic elements. The overall piece is a giant oriental garden long-scroll key visual, with the image using a large-area vertical gradient background: the top is bright and saturated cherry blossom pink and rose pink, the middle gradually transitions to soft light pink and light cyan, and the bottom transitions to a clear but obvious mint green. The pink and mint green blend naturally, with an obvious but delicate gradient, not too grayish-white, not desaturated to near white, the overall color should be bright, vivid, and visually impactful, while maintaining a premium feel. All scenery in the image must be uniformly rendered in "monochrome dark line drawing" style, absolutely no color filling for the scenery, no colored illustration, no color blocks, no realistic coloring. The line drawing color changes naturally according to the background area: in the pink background area, use deeper rose pink, rouge pink, and deep cherry pink line work; in the middle, use deep pink-purple and gray-cyan line work; in the mint green background area, use deeper mint green, teal green, and deep cyan-green line work. The line work and background belong to the same color family, but are clearly 2 - 3 levels darker than the background, creating a clear, rich, and layered visual effect. Strictly follow the reference image's oriental garden line drawing expression method, using very refined, dense, and continuous traditional Chinese garden fine brushwork, with thin but clear lines and rich detail variation. Increase the overall line density, so that the left and right sides, the top edges, and the distant areas have richer garden line drawings, not just a few scattered trees and buildings. The scenery naturally overlaps, interweaves, and occludes each other, forming a rich long-scroll spatial layering, but without being cluttered. The left side focuses on incorporating Yangzhou Slender West Lake and garden elements: weeping willows, Five Pavilion Bridge, classical pavilions, zigzag bridges, waterfronts, Taihu stones, bamboo branches, classical garden architecture, white walls and dark tiles, flying eaves, lattice windows, winding corridors, etc., unfolding layer by layer with dense line work. The right side incorporates Yangzhou garden and ancient city elements: classical pavilions, winding corridors, white walls and dark tiles, openwork windows, lattice windows, bamboo groves, pine trees, Taihu stones, ancient bridges, waterfronts, a small amount of spring flower branches, and can subtly incorporate iconic Yangzhou imagery such as the Twenty-Four Bridges. The tree and plant line work should be richer, with branches, canopies, willow branches, and bamboo leaves all depicted with dense lines, creating the lush but light oriental garden plant effect seen in the reference image. You can add more fine branches and leaves, distant tree clusters, rocks, water ripples, and architectural details to make the overall line work fuller. The water surface is rendered with extremely fine same-color-family line work, with dense water ripples, reflections, and distant shoreline lines, but no large areas of solid color. The architecture is also entirely line work, no white fill, no color fill, with only line density expressing distance and layering. The composition strictly follows the reference image's "left and right scenery expansion + large central negative space" format. The left and right sides are fuller with scenery, the top edge also has some tree and architectural line work naturally extending into the frame, and the central area remains open, creating a complete visual breathing space. Do not let any large scenery, bridges, trees, or buildings occupy the central core area. The central negative space is reserved for later addition of the tourism project theme text. The overall line work should be clearer, richer, and fuller than the reference image, but still maintain a light and refined quality. Do not make it traditional ink wash painting, no blur, no transparent fading, no hazy line work. It should have the refined texture of a high-end commercial art installation, an oriental garden art scroll, or a fashion brand key visual.
