Ok, to the person that brought up SCI-FI and bone looking wierd, the armor that Eldar wear is called Wratih Bone, it litterally is a bone substance.
I like the piece, the blends could use a little more work, especially on the green, the bone looks nice, but there are some areas on the claw that need to be cleaned up a bit, far too much dark brown showing.
That's very good painting. The "dirty" white is a great break away from the clean prissy eldar, the conversion is great too and IMHO this is a good model, even the base. Do work on the gems though, they look too much like paint and not a "shiney" gem.
