Wip - SkinShader in Arnold

As I promised, here is another work I'm doing these days, at the same time with DigitalEmily. I'm trying the arnold Alshader with the powerful sss option. Need these tests cause this year I will do a cinematic in Arnold with my university group! Stay tuned for other wips and works.
