I sketched this dragon's head from a live model, in charcoal. Okay, not actually from a live model. This was during the last day of Figure Illustration, and we had long poses from a model we'd drawn about 30 times before. Being just a tad bored, I drew this guy instead. It definitely drew upon what I'd learned in class, however, especially lighting. My favorite part of this drawing, besides the lighting and rendering, is definitely the eye -- it looks like the eye of an old and weary man.
