It's a pity there are so many people in the (close) background here, because there's something I find extremely striking about the redhead. It's more than just the flame colour of the hair, there's a confidence in the way she's carrying herself which makes her stand out (personally, if not entirely visually). If she'd had a little distance around her so that the others on the street were more faded this would have been an astonishing portrait, I think. As it is it's still very good. Alas the thing about street photography is that you can never get to control it; something which is both good and bad, in different ways.
