Wow, I love this image. A couple of things though which may cause your score to disappoint you. 1) The image looks to be tilting right when really the perspective has bitten you. It probably could benefit from a left rotate in any case. 2) Being a Shape challenge, you have broken up the shape so that it's not recognisable. Don't be discouraged though, it's a great architectural shot.
great shot...would have straightened it up in Photoshop though...although, maybe it was inteded to be skewed...love the colour and what the glass does to the Sky tower
