nice shot, except that there seems to be more light than shadow. overall it also doesn't present anything interesting. if there were more floors in this block that you took this, go up as high as you can, that might lend a more perspective view.
I like the concept and the arrangement, but I think the picture is hurt by the noise. The plain curves and lines as well as the smooth gray tones make for a very attractive picture. The noise destroys the smoothness and distracts from the simple elegance of the shapes and tones. I think the photo would gain a lot if you could eliminate the noise (maybe retake the photo under more favorable conditions?).
