Have you seen this man?

I've decided to focus on paintings with people in them next.  Terry helped me get started on this one in class on Wednesday, then I spent about 8 hours on it this weekend to finish it up. That really is a lot of time for me to spend on such a small painting (9x12) but the person that is the subject happens to be one of my toughest critics.  He's asked to remain anonymous.  Do you recognize him?
