Jesus, I like it! I think you need to get some emitters and set the lighting and sky right so that it sets a better mood. It would give it such a polished / finished feel.
Also perhaps take and redo the street and make it a little more, misshapen? I think it needs a slight slope or at least some more texture to it than being flat.
I just remember my ex-gf raving about the movie showing me some behind the scenes stuff and they had trouble with the architecture because they wanted the buildings to be like old and poorly put together so they had to like, purposely design them crooked and such. It was an interesting watch.
