Interesting perspective. The buildings are slightly out of focus, so I'm thinking this was handheld. I think a more focused shot would have helped you. The composition is off for me. Could you have included more of the buildings in the top of the shot? and adjust the composition to leave less "dead" space in the bottom left or adjust the crop. I would have given this image a higher rating if the focus was sharper and the composition was slightly different as mentioned. Just an honest critique.
The initial reaction is "whoa". Very impressive - almost as if one were looking at a staircase going straight up into nothing. The other buildings at the top of the image seem a little out of place, but it works as it is. One minor issue with DOF, but that can be over looked. Very nice.
