Personally, I think you could have framed this a little more towards the right, to enhance the already strong symmetry. And possibly cropped some of the bottom to fit a square format. The repeated light and dark lines produce a nice abstract feel that is a little bit diminished by having so much broken brick in the foreground. It's a good photo, truly, but I might be inclined to mess around with some cropping to see if it could be improved.
True enough, yes. Just thought it'd be interesting to experiment with the composition a little more. Not saying you'd need to get rid of this version, more like you might gain another equally good, yet different version.
