A while ago, I introduced my three year old to the concept of ninjas in the context of kids' stories she had heard at school.  This evolved into her demanding stories of ninjas and me creating Mei the ninja.  Mei spends a lot of her time being invisible and doing ninja magic.  As of now, we're up to eight different Mei stories that each mutate ever so slightly with each telling. 

Mei is inquisitive, bright, cheerful and a great vehicle to teach lessons. 

So please meet Mei.

As a technical question, I am using LUT 200 and the Iray extension. All of this is rendered native in CC. Does anyone have any tips or tricks for improving photorealism?  I have the avatar shaped to where I want her.  I have her hair and brows shaped where I want them. Somewhere between the roughness maps, the LUTs and IRAY lighting, we can get a little deeper into the uncanny valley.  I am just at a loss on how to do so.  Any ideas would help. Suggestions are very welcome.
