Right, so I have being wanting to do this for ages. Learn Zbrush, or rather learn anatomy and learn sculpting. I am not a stranger to the Zbrush. Used it over the years plenty but I have never put any serious time into it. Well this year I am dedicating lots of time to it. I have Scott Spencer's excellent book "Character Creation" armed with this and lots of anatomy books, going to get into it. Here is my first head. I took my sweet time over it, and I realize its not perfect, but it was great fun.
