Well here are two experiments I didn't bother saving.

The first one looks promising, not sure how I got that visible seam at the throat, though. The second was an attempt at a female face that looked more attractive skinless than with the godawful head room texture...and she doesn't look better from the neck down.

They're still a bit bland, and whenever I try to exaggerate just enough to add character intensity, I wind up with a painful looking cariacature.
