Stephen,
I really like what you've done with this figure. You have employed a painting style that I would like to try someday. I really like the clear definition of highlight and shadows.
Everything on the figure shows great detail because of your painting style. Very nice!
The only thing I noticed that looks a little out of place is on the close-up of his face. In that picture, it appears his right pupil (on our left) bleeds out a little bit onto the lower eyelid. It may be a trick of photography.
Thank you for showing us your beautiful work. I enjoy it very much.
John
