Had to google him, though yours was closer to his concept than mine appears to be. Masking the body from male>materials is probably what you would find the most useful for the rocky shape, the match to the head you used. As for the bare feet, they seem to give a more brutish feel, and I tend to add a bit of a fantasy flare to most of my creations, hence the sharper edges.
And just to clarify I really liked your character, hence wanting to try my hand at him. When I see a character that catches my eye, not thinking I can do it better, I just like to see what I can do with them in general.
The text is yours to do with as you please, use it, modify it, reference it, whatever, looking forward to what you do with him and future works.
