I hope you don't mind a critique, but the worm's eye view perspective used here makes it look like it was taken through a fish-eye lens, distorting the picture. The action taking place here is unclear and the scene looks a bit cluttered. A distance or overhead view might work better and enhance the impact. (:: like I should talk::
The picture is cool, I instantly noticed there was something wrong with it. After looking at it from a moment I noticed it was The gate columns, they don't seem to work with the pictures diminishing point. they just point to it. to get the proper effect you were looking for, the columns should have been slightly wider at the bottom and growing narrow at the top.
