想做一张广州的城市海报很久了，纯写实的建筑图看腻了，就想把小蛮腰塞进一条金色能量线里，让它像火苗一样从底部窜上去。黑到暗红的底子是为了把金压出层次，建筑用细线描加金色发光块的画法，飘在虚空里那种悬浮感我挺满意。底部那个白发女子是点睛，头发化成雾跟金光接上，整张的东方神话味就有了。
提示词补全了一版，光影焦点和文字排版都写进去了：
Flat illustration, high-end oriental fantasy city poster, vertical 9:16. Layout follows a diagonal, S-shaped flow from bottom-left to top-right. Background grades from deep black down into intense dark red, strong warm-cool contrast, faint stardust and film grain for depth. A flowing golden energy line winds upward through the center like a living flame — fluid texture, particle trails, gradient highlights, subtle glowing debris and volumetric light. Within the golden flow the landmarks of Guangzhou emerge layer by layer: the Canton Tower as the visual core with dominant scale, surrounded by the Zhujiang New Town skyline, Liede Bridge and modern Lingnan forms, all rendered as fine line-work filled with luminous golden blocks, crisp outlines, floating in a slightly fogged void for a surreal spatial hierarchy. At the base, an oriental white-haired woman, hair flowing like mist and merging into the golden light, translucent gradient strands, graceful posture, eyes closed, serene, holding a bouquet of colorful shimmering flowers — symbolizing the bond between people and the city's energy; character kept moderately simplified so the overall design leads. Lighting concentrates on the golden flow, buildings and figure outline for dramatic chiaroscuro. Palette: black and dark red base, brilliant gold as the main accent with rich light-dark layers, small pops of high-saturation floral color, restrained and refined. Integrated text: centered Songti "Guangzhou · China" at top, smaller date and author lines below in pale gold and warm white. Cinematic lighting, volumetric particles, clean and noise-free, ultra-detailed 8K commercial poster quality.
