hm to me it looks allmost like before,maybe the skin reflection is a bit better.
here you can load textures from a real scanned person,that you can load for the skin making as in the 3rd video.http://gl.ict.usc.edu/Research/DigitalEmily2/
btw in the second video he used a custom build shader,the video is still good to see and understand the renderings with and without SSS ect.
i would use the method from the 3rd video to make your skin.and as said from the link above, you can load a skin texture from a human scan,for stencil your own tex.
here i have a Emily testrender.Emily Human Project
