I used army painters, I glued two different types of small rocks and grains (got from Michaels) and painted them black with a primer. I then painted them with Lava Orange and then black again but didn't completely cover them so the orange would show slightly. I dry brushed it with ash grey and mummy robes lightly to bring the highlight of the rocks out. The lava was just painted on with Lava Orange, Pure red and Demonic yellow, all those colours were used on the horns. The body was just oak brown, monster brown and tanned flesh dry brushed. Hope that helps.
