A lower depth of field would have done nicely to minimize the background elements, but the crop has also achieved a good minimizing of their effects. The color tones work well together and her expression is priceless for the candidness. I don't find the border to be distracting or overdone and all the elements seem to be in just the right place. Bumpt from 7 to 8.
Very nice! Why is she making faces? Anyways, I prefer black and white for street photography but this one looks very nice in color. You did a good job.
