A bit of take off from the film 'Blood River'
It has triple dermis sss in cycles but I'll admit it needs more tweaking, or just follow another method...
I had missed the lower neck off the sculpt so i had to just model it and hand paint what you get there. I think it was enough for me. And I like the patchy facial hair. There really is loads to learn about doing this.
All done in blender with gimp used for the dermal layers.
