Or… just an industrial background could do the trick. 
That twin skull is such a brilliant idea and so perfecly matching to the disturbing (GOOD!) interpretation of Your Skeletor character.
Love it and sooo hope that you finish this one and share with us.
Thumbs up man (from a childhood MOTU fan) 
I have to admit, I was feeling like the original texture was too busy. The skull was such a similar color to the body that it just looked like way too much going on.
But as soon as you changed that body color, HOLY CRAP! It separates the skull (which I think is the focus) and it blends together so much better.The details are not lost, they are just not nearly as extremely contrasted as before.
This is looking so perfect. It’s great that you took to people’s suggestions here too, I think it has really helped your model out!
