Just as a small heads up/tip......

For the corrections on the mesh, I'm using a duplicate as a blendshape to adjust the mesh, this way if I overdo it or it looks wrong I can paint it out keep the bits I like and reduplicate the original with the new corrections and work on a fresh one.....

Also the inner eyes are using the misss fast skin shader. I have 3 maps on it, overall and diffuse color and a bump map
