Here's something I just whipped up over the past decade. Well, I started it about a decade ago, but have been giving it some more attention recently.
I intend to continue refining and perfecting it indefinitely, for use as the basis for whatever humanoid characters I may need in the future. In this instance I've given him an Anatomy Tools inspired makeover as a detail test for my newly revised 3D workflow. It's a bit rough in places - that's what tests are all about.
Sculpted and textured in Sculptris, modelled and rendered in Lightwave, with some displacement baking help from Blender. Some more details on the Sculptris forum.
