Im no pro, so take with a pinch of salt, but i like the subject and the focus, but as said before, the head in front of shot takes away from the image. I know that street photography is not easy and you have to take what you can get most of the time, but this image IMHO would have been better with a wider crop, a few steps arc to the left, and a seconds delay on the shutter to omit the floating head.
But hey, the hardest part is recognising the shot in the first place, and you did that just fine as far as im concerned.
Well done i say!
