OK, I was doing this when the winter themed build kicked off - the Santa hat is a tad tenuous but what the hell, cracking model, lots of detail and playing with inks, washes and different textures.
Hail Santahthulu - hat is from a Christmas wine bottle set!
Sans hat - really nice model, stands 180mm to top of head spiky bits.
Spent ages trying to do the monolith with inset green runes in black stone but never got it right - decided to go with weathered obsidian look instead, lots of detail to play with.
