It's good, but if that was your original plant than you really havn't much problem with stage 1. It's really hard to produce a map that really captures a real realistic level regarding streets and sidewalks. I mean to have everything like power-lines, phone booths, benches, bus stops, side markets, street lights takes a lot of effort to get right to make up a good map.
But yeah, you need a more pronounced definition of the building qualities. I guess suggesting more types of door-enterances is an idea, a lot of public buildings or apartments like you featured contain stoops. (Stairwells). Might want to try that.
