Excellent shot!! A perfect instant street photo, you captured an emotive and intense expression, a bit sad like an hard day is, congratulations. Peppino.
Maybe be better with a different background, but I know it's not easy to find the perfct situation, in any case I like the portrait, you captured a very deep moment, it's well framed and the B/W adds a lot of dramaticity, I would have contrasted it a bit more, but it's just a personale taste. Max
