Regarding Helm's anatomy, the anatomy was teh shit, but the pose was nothing like yours. So I made a Jad-type messy large-brush edit that tried to incorporate semi-realistic anatomy and keep the pose. his head is smaller, so that looks better proportion-wise. His arms are slimmer and less gorilla-ish. his neck is raised so that he has his head high.
otherwise, I think the edit speaks for itself :] Of course I destroyed your image at the same time :0
Otherwise, I think the lighting of the piece and the details like the hair and ragged cape and so is LE SHIT. You own at it. Start owning at anatomy and start to dish out pixel-ownage, you!
