Cool as heck! Also just nice to see a good background/enviroment piece getting a frontpage, sadly don't see those very often.
And good spread on the brick textures on the buildings, didn't go grinding like crazy, by filling in every single brick, wich would take forever to fill in, wich would probably also go by unnapreciated by most, but just enough bricks filled in, to have the material look convincing.
Car looks great too, though little bit weird how it slightly clashes perspective-wise, like its a bit of a 3/4 turned angle, while the rest is more of a full frontal view. Maybe a good idea to put the sidewalk and the road on that same angle as the car. But can definetly see the car looking more boring if was on a flat sideview to match the rest, so can't complain there.
Most funny little nitpick I noticed, is that the bicycle doesn't have any paddles, but you really have to zoom in and look for that to actually notice it.
