To my mind, the bone road one doesn't work with the full length Orc facing the viewer like that. I was trying to remember the many man-in-a-cloak covers of recent fantasy -- I think they are mostly depicted as if the man is moving, so the cloak/clothes are swirling around him, making him look active and dangerous. Here for my taste Orc is too stiff, too static, and looks a bit childish. So I think if you want to go down this path (ha!) he must be walking, and he must seem to be more dominant than he is, since this version gives the impression of a loser, which may be more accurate for the story, but isn't enticing enough. Personally, though, I'd show him in close up, head and shoulders only, perhaps looking away from the camera and down at the bones and the dead sea beyond him, so only in profile, to show his tattoo mask, with Otter on his shoulder staring boldly at the viewer.
I quite like the diving one, but I'm not convinced it's grabby enough, unfortunately.
