I like the contrasty style & the upright stains on the windows. I think this was very well seen, but a couple of technical points could've made it even more impressive. With a geometric composition I think its important to be picky - and get the horizontal beam at the top perfectly level (may take a little distorting in PS). Also the focus seems a little bit soft for a high contrast photo like this. Apart from these niggles, I like it a lot. Dunc
