Generate an urban-themed 3D paper-cut sculpture artwork, made from a single sheet of paper, where all buildings and elements must be connected through lines, bridges, flowing structures, or a bottom base — no isolated or floating fragments. City settings: 【City】: {fill in city} 【Core landmark】: {fill in landmark, e.g., Canton Tower / Oriental Pearl / Liberation Monument / Wild Goose Pagoda / Leifeng Pagoda at West Lake} 【Urban area】: {fill in area, e.g., Zhujiang New Town / The Bund / mountain-city night view / central axis of the old town} 【Material】: {fill in material, e.g., metallic foil paper / pearlescent paper / mirror silver paper / matte white paper / black-gold card stock} 【Atmosphere】: {fill in keywords, e.g., night view, dreamy, city lights, futuristic, oriental aesthetics} Image requirements: The work uses precise hollowed paper-cutting and a 3D paper-sculpture structure; buildings, roads, tree shadows, plazas, bridges, and decorative lines connect continuously on the same sheet, forming a complete city scene. The main buildings have three-dimensional layers, with distinct foreground, mid-ground, and background, like a gently unfolded paper model of the city. The surface has {metallic reflection/pearlescent luster/paper fiber/soft highlights}, producing delicate light-and-shadow variations under lighting. The background is a blurred city skyline, with faint building outlines, plazas, tree shadows, or distant lights. Add a few dynamic elements, such as floating dandelion seeds, star particles, light dots, scattered paper pieces, or city lights, symbolizing dreams, vitality, and flow. Overall style: high-end paper art, urban paper-cutting, three-dimensional openwork, complete coherent structure, realistic material, delicate light and shadow, high-definition detail, art-installation feel, urban tourism poster quality. Avoid: isolated buildings, scattered fragments, low clarity, ordinary flat illustration, plastic feel, excessive clutter, disconnected buildings, cheap cartoon feel, garbled text.
