I'am also a fan of Diablo's fantasy universe, so after i played recently released Diablo 3 game, i decided to sculpt smth from there - monsters there have amazing design, clear geometry forms and great textures. I was really impressed with the "Unburied" mob, so i decided first of all sculpt it I think it appears not bad)
As material i used Magic Sculpt + little Green Stuff. Body parts on base are Army Painter's "Battlegrounds" set.
It takes approx. 1 month to sculpt it from zero, and about 2.5 weeks to paint)
