Hi Jim,
This is a really good. I think it takes more talent to do older people. I mean, you have to make them look somewhat flattering, while making them look like themselves without making them look haggard. It's a challenge for me. I don't have much experience in pastels, so my comment is around the pose of the individual. Joseph said the chair bothers him. I don't think it's the chair, but the way the man is sitting in the chair. Is he sitting on the edge of the chair leaning back, not a very good ergonimic pose, or is his stomach out there? When I do a painting I try to make the subject sit in a flattering/natural way. If he has a slightly poochy stomach perhaps it would have been better to get him at a different angle?
I know. Apples and Oranges.
