信封里的世界 - hello world GPT Image 2 / Banana Prompt

A meticulously detailed 3D render, perfectly recreating the style, featuring an open, textured golden-yellow envelope centered on a soft pastel pink-to-blue gradient background. The translucent play button is removed. At the top center, the large, bold, cloud-like white text explicitly reads 'HELLO [CITY_NAME]'. Inside the open envelope, the miniature landscape is transformed to showcase the two most iconic and visually distinct landmarks of [CITY_NAME]. The foreground features a calm body of water with a detailed miniature of the first landmark, selected for its visual contrast (e.g., a modern structure, a specific bridge, or a sea-facing icon) situated at the end of a pier or platform. Behind it, on a raised level, stands a detailed miniature of the second, grander historical landmark, with crosses or defining features as appropriate to that building. Plenty of soft, fluffy white 3D clouds are interspersed throughout the miniature scene. The composition maintains the layered, surreal 'world-in-an-envelope' feel.--ar 3:4
