IBL? too slow for my liking, just use a sphere with a surface shader on it with your environment map.

With regard to the inner eye, I dont think the sss shader is doing it any good atm, and the phong E should pick up some form of spec....

heres one of mine on my site https://www.outlaws3d.com/?pp_album=m...Anders_08c.jpg
all the shaders here are blinn and phong. The blinn is using sss settings under the MR tab
