Technicals are fine. Color, sharpness, focus - all nicely done. Other than these factors this is a difficult shot to critique. With the crowd around, this seems to be a bit of a snapshot which is somewhat tough to get a very high score out of. The flag in the background really makes the emotion and steals the show with this shot but I think you probably already knew that. If you could set this up I think you'd want no other people in the pic and shoot with the flag a bit further away from his head.
Overall a very emotive shot and considering everything I'd say it's great.
Thanks for the opportunity to critique this image.
