Detailed Isometric City Map Design

I’m creating a game that revolves around exploring a vibrant, isometric city, and I need a highly detailed map to bring that world to life. The brief is straightforward:

• Style: Isometric, with crisp, game-ready visuals that feel alive at multiple zoom levels.
• Detail level: High—think individual windows, rooftop props, street furnishings, and subtle texture work.
• Core features: Iconic landmarks and varied buildings, an intuitive road and transit network, generous green spaces and parks, plus a few bespoke building types I’ll outline once we start (e.g., a futuristic stadium and a waterfront research lab).

I’ll supply rough sketches, reference photos, and a loose district layout to guide composition. You’ll translate these into a polished illustration ready for Unity/Unreal import. A layered source file (PSD or vector) alongside a flattened PNG at 4K resolution will cover my immediate needs; let me know if a different format suits your pipeline better.

If you have prior examples of isometric environments—especially bustling urban scenes—drop them in your proposal so I can gauge style compatibility. Looking forward to seeing how you’d visualise this city.
