This is a piece I've been working on for some time. I was inspired by a dwarven shield concept from Warhammer Online: Age of Reckoning that was further showcased on the Karak Vlag Wiki page for warhammer (http://warhammerfantasy.wikia.com/wiki/Karak_Vlag).
I thought "but what if a mountains lava flow was controlled by art pieces like these, almost like a sculpture?" and off I went developing a few substances and a zbrush sculpt that I combined together using material blends. Plus a quick hop through painter for polish. I'm satisfied with the product, but I found myself wanting to see it in a full environment. Time will tell if that tree bears any fruit.
