Suburbs

It looks really interesting, particularly from the player perspective along the street, however, from the screenshots, it appears players move from one end of the map to the other exposed along the street. It also appears you want the buildings to look like separate houses/buildings along the street, but if you don't provide some semi-continuous path toward the backs of the buildings, perhaps a mix of high and low, no one will have to guess which way the enemy will come from. I worry, as it is, players would find it boring just fighting on the street. From the bird's eye view of the entire map, it looks like you have a lot of budget left to add detail and interiors to some of the buildings to provide alternate and interesting routes across the map. That's where I'd start.

You might even think of adding a quasi-sewer network below, not one that allows you to bypass the streets entirely, but just something to add a few optional routes.
