Miniature 3D Architectural Model Poster: Feiyun Tower, Guanque Tower, Yueyang Tower, Yellow Crane Tower

Please generate a high-completion poster image of a “45° top-down isometric (isometric) miniature 3D architectural model” based on the user’s last input of 【theme / brand / model name】.

Core task:
Intelligently convert the user-provided theme into the corresponding brand store / building / exhibition space / conceptual model, and present it as a clean, refined, commercially presentable miniature diorama (miniature stereoscopic scene).

Input adaptation rules:
1. If the user inputs only a brand, model, or theme name: automatically extract its most recognizable architectural features, storefront elements, spatial language, the real brand color system, and brand character, and convert them into a miniature architectural model.
2. If the user uploads their own building/store/cafe photos: use that image as the main reference, preserve the building exterior, storefront, windows, spatial structure, material and color relationships, and unify them into an isometric 3D miniature model in this style.
3. If both image and text are provided: use the image building as the primary subject, and use the text only to supplement theme and style; do not automatically generate a title at the top of the image unless the user explicitly requests it.

Visual requirements:
- 45° top-down isometric / axonometric view
- miniature diorama look, toy
