手轻轻托着一个城市3D收藏级立体模型

Create a hyper-realistic 1080x1080 square render of a human hand gently holding a rounded, beveled miniature display platform showcasing a 3D collectible diorama of [CITY]. Feature its most iconic landmarks, small-scale modern and historical architecture, and lush miniature greenery and trees. A bold 3D “[CITY]” sign is cleanly built into the front edge of the platform. Use a refined, desaturated color scheme with matte textures to enhance the realistic scale-model look. Light the scene with soft studio illumination, warm highlights, and subtle depth shadows. Place the composition against a neutral gray gradient backdrop, keeping the same viewing angle and perspective for consistency. Add atmospheric depth, photorealistic textures, and ultra-precise detailing for an 8K quality high-end collectible aesthetic
