if i may throw out a critique, i think for the first and last ones it would be nice if you could manage to get the street in front of the first building in the picture. can't really tell you why, but it would be...umm...more...kosher? i guess for me...it would make me feel better....more natural i guess...i dont know, but i think it would help to have the street in front of the building
