I got that it was on a hill from the doorways, but the extrusion angle of 45º makes the perspective look a little funny, even if it's consistent everywhere and correct. The hill however, is incredibly steep when you think about it. Something bugs me about the square man-hole cover thing on the road but not sure what - perhaps the lightsource, not sure.
Perhaps some extra scenery would help to enforce the 'hill' intention, like a garbage can or milk bottles or garbage. These would sit at an angle (based on the normal to the street) compared to the doors and wall decorations. However, with the current steepness of the hill, you would wonder how it stays in place and upright.
