Looks oversharpened. The expression on his face is great! Came back for a second look. Still love the expression on his face. Change my thought on the oversharpened. He's just going grey. Definitely the expression gets it - 8 from me - good luck in the challenge!
A good sharp shot. Not entirely sure about the composition - including half of the body, but no legs - maybe a portrait crop would suit this better? The highlight of the shot is the face, the expression is superb.
