Perspective is great. Your title really captures the feeling when looking at this. I think your composition with the circle structure in the center surrounded by the skyscrapers pulls this together to be an interesting image. So is the building in the center of the circle really curved? or are my eyes playing tricks on me? Nice shot, my top pick.
This is such a great angle! But you're losing some detail in the pillars and circle that could be brought out a couple of different ways: If you use photoshop, the shadows/highlights command could help. Also, Topaz would be excellent on this shot!
My apologies if you already thought of these and chose to edit it this way. I just thought I'd make suggestions in case you hadn't considered it. It's such an interesting shot. (voting later)
