Death Guard Defiler

I've never liked the defiler model. I've always like the soulgrinder model better even though they use the same leg assembly. I just don't like how boxy it looks. So I decided to convert one for use in my Death Guard army since they are one of the few daemon engines that can be given the Death Guard keyword. I'm pleased with how it turned out, but I'm having difficulty with what colors to paint it. Here it is fully converted and primed.
