Had a tweek with the colour map in PS to get an idea as well as adjusted the spec map to get abouts what I want,

Its more closer to the effect that i'm after, Just find adjusting it on a sphere lit with a basic 3 point set up gives me a decent ball park for the final shader's settings, especially if theres lots to tweek, like using the SSS with a mix 20 shader too.

What do you guys think??
