This is just awesome. The first thing I can't help but notice is the perspective of the light above the buildings, that makes for some excellent contrast. It also gives it a feeling of an enclosed space in my opinion, as if you were trapped with nowhere to go, except for up, maybe, if you can get out, hopefully.
I also like how the buildings are arranged. It is actually quite intimidating (in a good way of course). And what is more, I have to remember that this is a photo, so that, for me, makes it even more special. Nice capture overall.
