Oriental Fantasy City Poster Design

Flat illustration, high-end city poster design in Oriental fantasy style, vertical 9:16 composition, overall using diagonal + S-shaped flowing composition, extending from bottom left to top right, with a deep black background that gradients to a rich dark red from top to bottom, creating a strong contrast of cool and warm colors and spatial depth, with faint star dust and grainy texture in the background. In the center of the image, a golden flowing energy line weaves like flames, extending from the bottom upwards, possessing a fluid texture, particle light effects, and gradient highlights, with subtle energy debris and volumetric light. Layering in the golden flowing light reveals the Guangzhou city landmark buildings: the Canton Tower as the visual core, prominently proportioned, surrounded by the high-rise buildings of Zhujiang New Town, the Liede Bridge, and modern Lingnan architectural elements, depicted with "fine line drawing + golden glowing blocks", clear outlines, rich details, seemingly floating in the void under the golden halo, forming a surreal spatial layer, with a slight fogging in the background enhancing the sense of depth. At the bottom of the image is an Eastern elderly woman with white hair, her long hair flowing like smoke and mist, naturally connecting and gradually merging with the golden flowing light, her strands semi-transparent with a gradient light effect, in a graceful pose, eyes slightly closed, serene expression, holding a bouquet of colorful flowers, with subtle glowing particles and star effects among the flowers, symbolizing the spiritual connection between people and city energy, with character details moderately simplified to highlight the overall design sense. Light and shadow focus on the golden flowing lines, buildings, and character outlines, creating a strong contrast of light and dark and visual focus, with an overall atmosphere that is grand, mysterious, possessing an Eastern mythological ambiance and slightly healing. Colors are based on black and dark red, with bright gold as the main visual emphasis, rich in light and dark layers, complemented by small areas of highly saturated flower colors, overall high-end and restrained. Text layout integrates with the image: centered large Song typeface at the top saying "Guangzhou·China", smaller text below saying "2026/04/20", and further below saying "LIYUE", using a light gold or soft warm white color, unified with the overall light and shadow. High-quality details, cinematic light and shadow performance, rich volumetric light and particle details, clean image without noise, ultra-high-definition 8K resolution, commercial-grade poster quality.
