Hborre: Thanks! I think I'm in a minority who seeks after realistic looking renders (even in fantasy!).

 The material room is a challenge. I have some idea of how it work-but have a long ways to go. I've learned a lot from BB and others (you as well)-and lots of experimentation.

The skin is EZ skin-but the teeth are my own tinkering node set up.

Quote - I intentionally left those parameters you mentioned off for the demonstration.  But, yes, anything to soften the specularity is perfectly acceptable to achieve an acceptable end result.  This is not so much achieving realism, but making the shaders respond accurately to the available light sources.  Understanding how the material room works is a huge challenge to many users.

Nice render, Eric.  She looks like she belongs in that scene.
