Good crisp detail and nice composition on this shot. Might have liked a touch of yellow from the pencil, but I like that you got so close in for this shot.
interesting concept for this phot. The composotion works well here clearly showing what you intended to show. Maybe a couple of marks that could have been cloned out.
I love that you have your puncher square in the middle. very diplomatic of you. I wonder, though, how many "Yes!" or "no!" comments you'll be getting. people love to speak their mind. ;o)
