Composition is nice, although the watermark in the middle of the pic kind of takes a way from it a little. ;)

Clouds are blown out and the really hot highlights on the building on the right are a bit distracting. Now that I'm playing with hdr I feel like I suggest it for everything, but to get the details in the clouds and highlights and maintain the details in the buildings, this is the kind of shot hdr would help a lot I think.
