great idea, but I wish you were over to one side so we could see his eyes or more of his face to give him an identity and see more of what he is doing. :) Nice use of doutone.
Wow, what an amazingly neat subject for a photo. It does meet the challenge, in an unusual and strikign way. I'm trying to decide if I think the man should be a little further to the right so there's no negative space on the right edge of the elbow; I think that might have been a little nicer. Top to bottom is fine, though.
I really like the lighting and of this photo. It is crisp and clean. The duotone is fitting. I feel it meets challenge. I only wish I could see more of the face of the performer. 8 Good luck in the challenge.
