i almost wish that top portion were cropped...

Wait... I thought we had finished with "Look Up." Just kidding, nice shot, though it doesn't seem to work for negative space IMO.

I like how you managed to use two kinds of negative space to convey mystery. it looks as if you are looking up a tower in the daytime based on the highlights at the top, but the windows are black. I like the composition very much. the soft light at the bottom right is distracting.
