Lighting:

I use a 4 points lighting.

Skin Shader :

I use the MR'SSS Fast Skin Material, with some tweakings. I plug the normal map mixed with the bump shader into the 'Bump shader' slot, and the diffuse map in the 'Overall diffuse coloration' slot.

Final Render:

So, I launch the final render with occlusion in another pass...

and compose the final image in Photoshop.
