A very good candid which matches it's title - nice capture with a lot of definition, good off center subject and very gentle properly controlled DOF. While the image has a lot of plus factors, the rather narrow crop could be viewed as a negative, but in this case it works extremely well. The contrast between the subject and his surroundings is interesting - a commentary on a solitary soul vs the rather social gatherings the subject is set with. Very nice job and good solid photojournalism.
I think a tight in shot would have been better but maybe you wanted to show the environment or you didn't have a lens allowing a tighter shot. Wow, you can really see his emotional state. B&W was a good choice. There's a story in this one. Good luck on the voting.
