I looked through all the photos before voting and commenting. This was the first one like this that I saw. I believe there are about 4 very similar. However, this one grabbed me and it still seems like the one the works the best as a pleasing abstraction. Whether that was random fortune or very careful framing (or cropping) is your secret to keep, as far as I'm concerned.
The contrast could be upped a bit for some darker darks but I wouldn't want the lightest greys to go much lighter.
Quite a nice approach. maybe more contrast might have brought out the geometry more strongly, though of course it would require care to keep the grey day feel that you have. Reasonable composition, but the top rioght corner disturbs things a touch.
