One of the first things that (-need) (+needs) to be understood is that from a very far distance, the Subsurface Scattering effect is harder to perceive. This means that it is best to have the Base Color of your texture looking right when viewed in the distance. You could also use a grayscale texture to darken the base color and the specular (caused by occlusion) to give an overall better look to the skin. You can also add some Vector and Scalar controls to adjust the color and power of the skin to help you further tweak to get the look you are after.
I am really not going to give anymore feedback on this particular page because there are lots of other programs and people that do a much better job of human skin than I ever could. I am actually looking at mixamo for most of my human character needs.
Cheers,
