I am playing with the PBR, my early replication of the posted node set up left me with the skin WAY too shiny. I added a fresnel node. My favorite lighting is EZDome 2 with some high resolution HDR's and a single "sun" light. Here is a comparison of my latest iteration. With Cycles on left for comparison. Still needs work- a little too much red scatter. The displacement node with + and - maps and using the math node is a carry over from the character maps. Seems a bit odd-but works for fine lines in face-of course I am Subdividing the mesh.
