Going up later today - Set # 4...This is a lighter gray set than the first 3 with a slightly lighter Jade clear tint crystal Demon head. If you miss out on this set I'm working on another one or two (I'll know in a little while if the molds are still holding - most of them sat around for long time).
This set of sculpts got a Daily Deviation on Deviant Art - http://arthammer.deviantart.com/art/Monster-Magnets-158316403 (very humbling....).
