Create a vertical 9:16 high-end oriental fantasy city poster for [City]. Use a flat-illustration poster style with cinematic lighting and commercial-grade detail. The composition flows diagonally in an S shape from the bottom left to the top right. Use a deep black background grading into intense dark red, with faint stardust, grain texture, warm-cool contrast, and strong spatial depth.
Place a flowing golden energy line through the center like flame, extending upward from the base, with fluid texture, particle effects, gradient highlights, subtle energy debris, and volumetric light. Inside the golden flow, show the architectural landmarks of [City] emerging layer by layer. For Guangzhou, make Canton Tower the visual core, surrounded by Zhujiang New Town skyline, Liede Bridge, and modern Lingnan architectural elements. Render buildings with fine line drawing plus golden luminous blocks, clear outlines, rich details, a golden halo, and slightly fogged background depth.
At the bottom, add an oriental white-haired female figure with hair flowing like mist and naturally merging with the golden light. Her translucent hair has gradient lighting; she has a graceful posture, closed eyes, a serene expression, and holds a bouquet of colorful flowers with shimmering particles, symbolizing the spiritual connection between people and city energy. Keep character details moderately simplified so the overall poster design stays dominant.
Add centered Songti typography at the top reading [City] · China, with smaller text [Date] and [Author] beneath it. Use pale gold or soft warm white typography unified with the lighting. Keep the atmosphere grand, mysterious, oriental-mythic, slightly healing, and sophisticated, with black and dark red as the base and brilliant layered gold as the visual focus. Avoid incorrect landmark identity, unreadable text, extra watermarks, messy particles, distorted face or hands, broken architecture, noisy low-quality rendering, and flat lighting.
