Great conversion, nice muscle work, very realistic muscles. There's real movement in this mini, It just look like He ready to pound the ground into obliviness. But the arms are to differently tilted to be held in that position, just hold your arms like he does and veel how odd that feels. It comes out more naturaly if it's more balanced.
Good luck withpainting him, he looks like fun to paint
Looks pretty good, I like the growler head, you most have tore that off of the growler ring. lol It is hard to work with these mini's looks smoothe, good work.
