Went back into this one and corrected some of the coloring and drawing errors back at my studio, after the workshop was over, and aimed for a simple, 3-value composition. There are still a couple of spots on the face where values need to be corrected.
Specifically, I'll ask Peggy because she was there

, should I push the area between the cheekbone and the jawbone to a middle value? Of course other opinions are very welcome.
Size is 20" x 24", which seems a little large for a workshop portrait.
