Shanghai
Afterglow

Use case: stylized-concept
Asset type: vertical web gallery artwork
Input images: reference images for brushwork, palette, composition and print texture only; do not copy their exact scenes or layouts.
Primary request: 原创一幅{城市}的{具体局部机位}绘画，主体是{地标或建筑片段}，加入{一个前景框景元素}和{一个适度的度假化借景符号}，不画完整城市全景。
Style/medium: rough hand-painted gouache and acrylic editorial illustration fused with limited-color screen print; broad flat blocks, coarse dry-brush, broken edges, scraped pigment, irregular halftone dots, visible paper fibers, slight ink misregistration.
Composition/framing: 4:5 portrait, one large foreground frame, 50–70% open sky or quiet negative space, layered middle ground, one small landmark anchor, a simple diagonal or horizontal rhythm.
Lighting/mood: {时间与天气}，松弛、开阔、带一点城市度假感。
Color palette: cobalt or cerulean sky, deep indigo shadows, violet or magenta transition, coral accent, warm cream and citrus yellow light, restrained leaf green.
Mark language: distant windows, lamps and reflections become sparse hand-placed dots and short broken dashes; keep edges imperfect and visibly handmade, never overly detailed.
Constraints: keep the place recognizable, preserve the rough print surface, and make the scene original rather than copying the reference composition.
Avoid: photorealism, glossy 3D, smooth AI gradients, hyper-detailed windows or leaves, dense skyline, readable signs, logos, watermark, cyberpunk, collage, and exact artist imitation.
