Here are some test renders using the skin shader from the Girl With the Wind In Her Hair .blend.

The skin shader is a completely reworked Henti/Gillan shader that is a little more difficult to use but is, in my opinion, easier to tweak. In case it isn't already clear, I mean to say that the Henti/Gillan skin shader is very useful in its own right, and this doesn't replace it. :)

This shader is, by default, a little more suited to a darker-skinned individual, but as you can tell from the renders, various sorts of white people are represented, too.
