Finally dug up an old project I made back in august, but couldn't get my hands on untill now.
It's unfortunate that now I clearly see that the sculpt itself is pretty weak but I didn't want the time spent on him to be wasted for nothing, so here he is, Thanos' yonger brother as they say.
This is my first try with zBrush-Substance-Arnold workflow which I actually enjoyed quite a bit. My "fear of render" is wearing off finally, just gotta get good at it.
