Beautiful portrait. Excellent detail, nice matching tones between the jacket, background, beard and hat that really set the face and eyes off and bring them out. Good capture of character. 10
Excellent portrait. Exposure and colors work well. I think a bit more background (though I do like his face filling the frame) would help to tell a bit more of a story.
I like the border.. I wish that you cut out the ear on the left and maybe had him more on the left side of the picture with a little more neg. space on the right. Good job!
