So now that I've gotten into a more sculptural program, Zbrush, I'm finding that I want to do more realistic sculpts.  I've quickly discovered though that I've spent too much time over in cartoon land and most of that knowledge of anatomy that I learned years ago has escaped from my brain and is running amuck somewhere.  So I'm going to start the process of relearning anatomy and hopefully jogging my memory.  Tonight I started to rough out a skull in Zbrush.  I started from a polySphere though, which is one solid surface, and of course the skull and the jaw bone are separate pieces and the skull has a "hole" in it, or more like a bridge on it, namely the zygomatic arch (ha, I still remembered that).  So, now I want to go in and rebuild my model so I can include these features properly.  I'm going to attempt to rebuild it entirely in Zbrush to force myself to learn what the program is capable of doing.  I'll update the post and let you know the results soon.  Here is the rough skull so far.
