Big Form Modelling Phase

The past two weeks, I've concentrated on starting some big form modelling in the whites, and refining some shapes while I'm at it... On the head, there are four areas in the lights that I'm defining: the forehead/cheeks, the beard, the hair, and hte neck. I've just started on the face/beard. There's still some ways to go but the forms are beginning to take shape. In real life (not this photo), the face values are in fact darker than the top of the beard or the hair, so I'm keeping that in mind.
