Help with my city layout

I dont really know if its the right category, but I designed a minor scale map for Detroit and surroundings and I wanted to know feedback of more experienced developers. The game will be gta like and I was thinking in making something between gta sa and gta 4 in the terms of realism.

I had a way bigger map but I had to scrap it out because I wanted to make a minimap but roblox dont support 4k images

The map will probably be 30720x30720, thanks for any help!


this seems pretty darn good to me i like the island idea it reminds me kinda like New York exept for the highway
