I spent several hours trying many different variations inside the SSS channel, and couldn't get anything to look good. Then, before turning off the computer, I decided to scale V3 up 1,000 % (Making her a little over 10 feet tall). This made all the difference. The first image shows her with the default wax material applied to the face and scalp, and only approx. 13" tall. A small spotlight is directly behind the ear. The second is her resized, with the spotlight sized the same. She clearly appears much more organic, with thickness variation apparent within the ear, exactly as I wanted. Image three is the same, only I increased the size of the light to cover more of the head. Thank you Mark and bwtr for your input, it's much appreciated as always. It's funny how simple the answer can sometimes be.
