Cinematic lighting poster: GPT Image 2 prompt

Flat illustration, Eastern fantasy-style high-end city poster design, vertical 9:16 composition, overall using diagonal + S-shaped flowing composition, extending from lower-left to upper-right. The image uses deep black as the background, gradating from top to bottom into intense dark red, forming a strong cool-warm contrast and spatial depth, with a faint stardust and grain texture in the background. Through the center, a golden flowing energy line curls upward like flame from the bottom, with fluid quality, particle light, gradient highlights, and localized energy debris and volumetric light.

Within the gold light, Guangzhou's landmarks emerge in layers: Canton Tower as the visual core with prominent scale, surrounded by Zhujiang New Town high-rises, Liede Bridge, and modern + Lingnan architecture. Buildings rendered with 'fine line drawing + golden glowing volumes,' with clear contours and rich detail; under gold halo they seem suspended in the void, forming surreal spatial layers; distant view slightly atomized to enhance depth.

At the bottom is an Eastern white-haired woman, long flowing hair like smoke and mist, naturally connecting to and gradually merging with the gold light. Hair strands are semi-transparent with gradient light; pose graceful, eyes slightly closed, expression serene; she holds a bouquet of multicolored flowers. Glowing particles and starlight effects scatter among the flowers, symbolizing the spiritual connection between humans and the city's energy. Character details are moderately simplified to highlight the overall design feel.

Lighting concentrates on the gold streamline, buildings, and figure outlines, forming strong light-dark contrast and visual focus. Overall mood: grand, mysterious, with Eastern mythological atmosphere and slight healing feel. Color palette: black and dark red as base, highlighted gilded gold as primary visual emphasis, with rich shading; small areas of high-saturation flower colors as accents; overall premium and restrained.

Text layout integrated with the image: at top center large song-style 'Guangzhou · China,' below smaller '2026/04/20,' below smaller 'LIYUE,' in light gold or soft warm white, unified with the lighting. High-quality detail, cinematic lighting, abundant volumetric light and particle detail, image clean without noise, ultra-high 8K resolution, commercial-grade poster quality.
