Well, a part of the problem I'm seeing may be from working with non-human skin tones. AD&D players may have heard of Drow. But the spot sizes seem to work on a V3-style head, yet look horribly blotchy on the body. I haven't got as far as the sub-surface scattering, but so far the fiddle of setting up the basic shader seems worthwhile. It'll be fairly easy to try it with another texturemap.
