Thanks for your patience. You're right I am just getting familiar with the material room, and haven't tinkered with nodes at all. I will follow your suggestions and consult the manual.

Just to clarify things, what I am doing is basically modifying the specific skin of this figure? Once I make the changes I can change lights and the changes will improve the end result... When I say "skin", I am of course referring to the shaders embedded in the skin, if that is the correct terminology.
