Looking great Jay, could you show the ref shot you are using for the pose, I know there are some great zbrush models out there but do any make there way to production or animation. I do think you have a lot more control in maya,lightwave or modo and use zbrush or mudbox for finishing off the mesh to get a normal map...........dave

Edit:on a side note some women of that time used to have there back teeth removed to get that jaw look not saying Audrey did?
