I didn't quite understand what you were saying about people on Facebook: Did you mean they have a chance to win a free drawing, or they got to vote on who they would like to see you do a portrait of?
This chap looks great as usual. I'm wondering about his upper front teeth appearing blue. Is he wearing some kind of a protector like football players or boxers use to protect his teeth from the puck? If it's for protection I would think you would want it to protrude more -- to look bigger than where his teeth would be. But since I don't know hockey gear it may be suitable to make small. But my feeling is that right now it looks like his upper teeth are blue.
Anyway, a fun piece and it never hurts to put in the puck -- meaning it only hurts when it hits the body but it very much adds action to the painting.
Nice job!
