Realistic Blender Environment Modeling -- 2

I need a seasoned Blender artist to build a fully-realized, realistic 3D environment from scratch. The focus is pure 3D modeling—no animation or texturing work is required at this stage, although clean UVs and logically named collections will make later texturing easier.

The scene should hold up to close-up camera work, so accuracy in scale, believable proportions, and efficient, optimized topology are critical. Please use only native Blender tools (Geometry Nodes welcome) and keep the asset non-destructive wherever practical.
