Nice details. I think that the shadows really match the position of the building. Though, I am not satisfied with the mood that you are creating. The image looks dry and I am able to look at it in a way that I could appreciate it in it's full potential. Try to add a mood on the street. I think you are giving us a clue that the street must be hot. Try to emphasize that by adding people with umbrellas or something. Also, The building blends with the floor. If the sun must be on the upper left portion. The floor should be darker because of the shadow of the building.
