I've seen the female head before in a magazine... (no not that kind, a graphics mag). They showed
5 heads to a bunch of people, 2 rendered, including this one and three real. The pople had to say
which were the real faces and which were rendered... And nobody chose that one. The reason?
The face is asymmetrical just like in nature and she has small blemishes in her skin and bone
structure. They made sure that it wasn't just half a skull mirrored, and people wanting to model
faces try to make them just too perfect. Apparently that's what made her look more real than the
others.
This can be seen in the lower picture where the face is slightly too symmetrical, although the bone
structure is nicely done.
