I'm with Larb - the 3d version is superior! Okay, a street map has a different purpose. If you need one, I like the simple network of red roads better than those with blocks of buildings. That one seems to show the layout better. Plus, the way the two with buildings are constructed, only the interior of blocks have buildings. That seems implausible... I would figure especially the districts up on the hillside would have some houses and shops on both sides of the uppermost and lowest roads.

Nice work, whether done or not. I hope you'll be entering some contests (well, not the ones I enter!).
