This was made in mudbox 2009 with the starting head in an hour or two with no reference.
Really enjoying sculpting heads in 3d. It is the face people are drawn to and really heads are fast and fun to draw or sculpt. I just never imagined I would be able to sculpt heads in a reasonable amount of time. Trying to get a realistic head modeled in zbrush and mudbox out of spheres is fun and challenging.
Portraits have always been fun for me.
