OK I was pretty worried, knowing that Blizzard used to label all kinds of monsters "centaur", things that have nothing to do with what a centaur is (half human, half horse). Just look at the neutral creeps called centaurs... :/ being a horse-lover, expect a centaur to be an actual half-horse creature, and not some blue skinned half elephant and half demon like "thing"...
So all in all I'm relieved with this result. I'm still a bit unhappy with his monstrous head (horns and canines etc.) as in my rendering the other half of a centaur is a human, and not some kind of humanoid monster, but I can still live with this, as at least his lover body is indeed a horse body, and his upper body is quite human.
Don't get me wrong, the artwork is pretty nice. I'm just a freak like that when it comes to mythological creatures, I don't like great inaccuracies. So once again, other than the face, I pretty like him.
Nothing special, really. I'm picky on Centaur because centaurs are mythological creatures who are already defined, but in the case of Magnus, there is really nothing to adhere to, so it's all up to artistic freedom from that point.
