I had thought maybe I shouldn't post any more 3d stuff til I got to render stage, but then I optimistically decided that some people might like seeing the build in progress, and those that don't can just ignore them til there's something pretty.
So here's a shot of the mostly completed face with the wireframe turned on so show off how well Sculptris retopos the mesh and the dynamic topography (the dense spots on the arms are accidental touches).
It'll be pretty awful for rigging and animating but it's awesome for what I'm using it for, especially when I finally learned to mostly ignore the mesh and got comfortable with the process.
