Excellent composition, and I love the colours. There is a little graininess in the bottom right dark area which is a little distracting, and some jaggies on the diagonal lines near the top, but still a very nice photo. 8
nice shot, but too impersonal. for this situation i think you might have been better served getting closer to the wall and making the grid dominate the photo as opposed to being a muted part of a bigger constrution.
