3D 미니어처 도시 홀리데이 장면 프롬프트

Present a clear, 45-degree top-down isometric 3D miniature cartoon scene, depicting the classic architecture or landmarks of [City], and place it at the exact center of the composition. Decorate the city with festive ornaments, twinkling lights, and appropriate [Season, default Winter] or holiday details, making it a vibrant [Holiday]-themed city. Use soft, detailed textures, realistic PBR materials, and soft, realistic lighting, with subtle shadow effects. Create a small diorama-style city base with clean edges. Use a clean [Holiday] background color that contrasts sharply with the scene. At the top center, display the text [City] in bold, large letters. Directly below it, display "[Holiday] Special Edition" in medium font. (Optional) Place a small square flag icon below the text. All text must automatically match the background contrast (white or black). Composition: perfectly centered, 1080x1080 square, ultra-clean holiday diorama aesthetic.
