I'll be honest. I think the composition is too busy, my eye wanders all over the place, and I don't get a sense of 'urban war'. The conversion has left the shadows a little too dark for my taste on this *particular* image. A little too much contrast?
I like the idea, and I understand that it was probably a quick snap, so take these words with a grain of salt and understand that this is just my opinion on this image.
