Human skull zbrush sketch (WIP)

In my ongoing study of the human body I decided to try a human sculpt today. Thanks to the short break from school I had some time to do some personal work. After trying my hand on a nose and ear, i decided to tackle the skull. It was somewhat challenging, but overall I'm pleased with the way it turned out. However I do think he needs a visit to the dentist...
