Apologies for those who commented before, I couldn't answer because my computer broke. Lost 2 weeks work :(
Anyway I think the texture is only lacking slight touch-ups. It has taken me 3 months to make by trial and error. (I am so much wiser now ;-)
P.S. The eyes don't have inbuilt highlights and the actual texture is lighter - so that the skin is easier to modify by playing with the material colors.
Comments and critisisms (how do you spell that word) would be greatly appreciated.
