The original, basic sculpt was made in Sculptris. While I'm trying to convert to Blender sculpting tools, Sculptris still holds the cards for intuitive controls. Once exported as a .obj file, everything else done in blender.
The retop process has allowed for the model to be an easily animatable mesh with decent edge loops around the eyes and mouth, minimal poles and zero triangles (I think!).
I've used diffuse, normal (baked from the sculpt), bump and specular maps on this model.
There are also several vertex groups controlling the the hair (separated top and sides), brows and stubble.
An animated pan around the model can be found here
