Great shots. I love the subjects. The only thing I will say is that I don't think you should have the selective colouring on that one before last. I'd like to see it all in colour as there's a lot of detail lost in the lady's face, or all in b&w with the contrast bumped up a bit.
this reminds me when i was in poland, i wish i could of gave these peoplemoney but i rarly had money on me, it really hurts seeing people like this, great example of the world we live in
