Wraithknight W.I.P part 2

This is the current state of my wraithknight after i attacked it with a paintbrush again. He is slowly getting there, and is looking a lot better, but it is obvious i still need to do a lot of work to him. Next on my list to do on him is to go over the bone again, its very messy at the moment and i need to get it a nice even colour. The metal needs another highlight and wash.  The guns are a big thing to do but i will go over them again later on.

I am happy with how the purple has turned out and now i have added in a few other colours, i don't think its too much of a block colour, which is something i was afraid of originally. The bone colour on the shins really helps and stops the head looking out of place in so much purple. 

Spirit stones, i have decided that i am only going to paint the chest gem as a spirit stone as i hate painting them and the rest can just be asphetic bumps, the eldar love their bumps. A big thing that has come as a surprise for me is the groin plate, it looks very empty. I have looked at all of the games workshop ones and they have their craftworld rune there, and as of yet i haven't come up with one for Dem-Kirath, maybe its something that i should invest in creating. That would involve setting their back ground in stone which might not be a bad idea. 

So what do you think of him so far? and what kind of shapes would you use for creating a new craftworld symble?
