Robert,
very good sculpting. The facial expression is very good, and the feathers you sculpted would have been a challenge! Congrats on pulling two of the harder types of sculpting (and painting!) off.
I agree with ken; The sash has two things to it. The first is that some of the creasing (drapery; how fabric behaves under gravity and so forth) looks a bit odd. Check out images of togas for an example of how fabric may behave when worn over one shoulder.
The shadows of the sash seem a bit dark in some places where they shouldn't really be. Perhaps tone down the shadows a touch where the fabric rides up on the shoulder, will distract the viewer less.
Still, that is a great face, full of character! (particularly the laugh lines around his eyes, neat touch!)
Thanks for sharing
