I know this is a candid street shot...but I'd have loved the BURST of color to have been the guy behind the table in the gray jacket instead of the GO player.
The colour is subtle and is pulling attention directing it to the players hand, I feel you have exceled at meeting the challenge but the image needs to be sharper at the hand where all the attention is being drawn. Nice composition.
I like this picture :) The red jacket, the extended hand, and everyone's gaze all reinforce each other to draw attention to the subject. I wish more of his face was visible.
