Pretty nice. I didnt even know that they made a model for him. The pink is a little hard to follow, as Im almost sure he didnt follow Slannesh, but it has its own sinister aspect. More highlighting on the black fur. Good job otherwise.
His black patches of fur needs a few more highlights. It's hard to see the fur without it. And his teeth on his tail needs darklining inside the mouth to make his teeth noticable. But that pink skin and bone is great!
