Pretty awesome dude. I love the material on the bone. The weapon is great too. And I really like that fleshy material connecting the ribcage and the pelvis. It adds a nice touch. The skulls could be a bit more anatomically sound for my taste, but that's just me. Good stuff man.
Good work so far! The character is looking a bit flat to me and could use some color gradient and hue-shifts to help make it feel richer. Also might think about tweaking the value on the skulls on the shoulder pad and belt to make them stand out from the other bone surfaces. The runes on the blade also could be pushed in…
