very nicely observed. the balance of patterns, lines, tones all work to keep this interesting. i also like the juxtaposition of the soft clouds with the strong buildings. strong work here!
This is a neat shot! The dark sky reflected in the building on the left helps keep my eye focused on the more interesting main building. The way all of these lines converge also really helps this composition. You did a good job with the touchy area at the top right of the building on the right. That contrasty area is very nicely handled. That side of the building could have easily been blown out, so nice job. The only thing I might do differently is to very slightly burn the upper right corner. I think it would benefit this a bit. I cant help thinking what this would look like in infrared!!
