It's the lady on the right that makes this picture for me and I think your PP just makes her a little less visible. She looks to me like a little old lady scurrying away from the dark figure in the background (I'm sure you are aware of where this is taken Pete). I like the desaturation that you have done, but it's just a tad to dark for me. I would however, looking at it again consider a crop just above the puddle on the right.
