Wow, magnificent shot. I love the grain in this picture. It, together with the white border lends to the mood and feel of this capture. Shooting a true candid can probably have its limits in terms of timing and background, which is why I am assuming you chose this close crop. It works wonderfully though. Well done on a great shot.
I don't usually like comments or give them, but since candids are near and dear to my heart, I have decided to comment on every photo in this challenge.
Overall a bit grainy for me. I also don't like the white frame. Takes the mood away. Should have been black. However, still a nice candid moment, but would have liked to have seen more clarity. A 5 vote from me here.
