With this post I begin my sketchbook blog of sorts.
I'll start where I last left off on my web gallery www.ElliottMitchell3d.com.
Above: The stone looking head is an evolution of an earlier head I created for Thing-A-Day.com. I modeled it in Maya and Zbrush. The material is courtesy of Aaran Lewis on ZbrushCentral.com. That shot is rendered in Zbrush.
Below: I'm working on a Sub Surface Skin Shader to render in Mental Ray. Same mesh.
