I am just experimenting with alternate SSS shader with Subdermis & Translucency Texture(look at ear) Support but no Gloss/Decal Support that is similar to marmost skin shader.
There are shadow problem that maybe coused by shadow solution used in vam I am not sure, and very strong bump effect that may be solved by adjusting normal map.
It will take too much time and effort to solve them.
Last Image is original shader.
