I was going to post this last week, but got sidetracked until now.

This image is very aesthetically appeasing. I love the repetition, and the different reflections and light patterns in the windows. It's almost visually confusing, which keeps my attention longer. Does the building keep going back like that? Or is where you cut it off the end?

Not bad at all, but it might have been even more effective if there was a good reflection going on in the one window on the left. Try an adjustment or two in PS to make it even more abstract.
