I think the Avatar was on the first models I got years ago and I also think he was the first I attempted to paint and did a shocking job as well. So I am currently in the process of trying to salvage him lol and then finally finish painting him. He is one of my favourite models to field and I don't think I've played a game without him.
I initially started painting Eldrad here in the Ulthwé colour scheme but discovered a much nicer colour scheme on the Games workshop website. I really love blue gems! he's probably about 50% done here
