This is a character design I am currently working on. I have been focusing on learning subsurface scattering for the skin. Also, this is my first attempt at transferring normal maps from Z-brush to a lower poly mesh in Maya. Any feedback you can offer would be greatly appreciated. Thanks!

When working with SSS it is important to work to some sort of rough scale (not sure if I am telling you what you already know) make sure your character is scaled up way bigger than the grid so that the depth and level of the SSS will be right. Then I always take my colour map and blur is and saturate it and use that as the epidermal map. Always works out nice.
Would be cool to add some veins and stuff like that to that epidermal map too.
Not sure if I helped at all but there you go
