The Sorcerer bits are Evil Craft, who may or may not still exist. I need to check that seller on eBay I found.
Fire Raptors are fine provided you can get the sides as true as possible. After that everything else is a doddle.
I like the sorceror - really different look and I like the dynamism of the pose.
What are you going to do next with Daemon prince? I would like to see that coming together.
