城市文旅海报

Create a vertical collectible narrative poster for [城市/主题]. The poster should focus on the cultural identity of the city rather than a commercial logo. Build a rich city universe using recognizable landmarks and symbolic elements: [地标 1], [地标 2], [地标 3], [自然景观], [文化符号]. Use a strong central silhouette or symbolic structure that represents the spirit of the city, such as [主轮廓载体，例如 guardian beast / ancient gate / mountain shape / river curve]. The style should be high-end editorial poster art, detailed but not cluttered, cinematic lighting, refined colors, strong composition, collectible quality. Leave clean reserved space at the top and bottom for official logo and final typography. No readable text, no Chinese characters, no English words, no numbers, no watermark, no fake logo.
