I wanted to do some anatomy practice so I decided to make a generic base head model that I'd be able to use for a number of sculpts. I don't like the Mudbox base head as it doesn't have an open mouth or eyes. So I made this one. I also made a set of teeth, gums and tongue although you can't see them in this one.
Although I plan to do a set of more characterful heads, I thought I'd start with a plain and generic one. What could be more plain and generic than a bald space marine. :)
