The Second Part of the tutorial is more of an explanation on what I've done rather than step by step.
Here is a link to Part 1
I used VMC Purple and hit the high points of his head and hands.
I then used a 50/50 mix of VMC Purple and VMC Pink to do the extreme highlights.
I used Dheneb Stone for the claws and teeth with first a Devilin Brown wash.
Once that was dry I went over them with Gryphonne Sepia.
I used VMC medium blue for the highlights on the body.
I used streaks of all three colors throughout the hard chitin sections of his armor
