Looking demonic! It looks refreshing having a demon without the traditional dark and red colorsheme too, turns out green and blue work well for evil. :) A lot of detail in this! It's a work of art!
For some reason the first thing I thought when I looked at this was "Yrmgarl-symbarch (XXXL) vs. Farseer"which is kind of weird as HPL and 40K are just a slight bit apart. Then again I guess HPL influenced a lot of modern artists and writers so why not?
I really want to make that picture into minis now - to bad my painting skills arent nearly as elaborate as my comments xD.
