I'm not familiar with the character, but that means I'm judging this pretty much for its aesthetic value as I see it *laughing*
It's a very, very clean, beautifully-executed piece of manga-style art, and better, in my opinion, than a whole lot of manga.The figure is maybe a little elongated as far as the torso goes, but that's not uncommon in manga illustration, and doesn't really detract. As it is, he projects menace and twisted authority; the lowered head, the huge weapon held easily behind him, the Nazi-style uniform and monocle all resonate evil power - the combination of modern (uniform) and ancient (weapon) suggest that his evil is almost archetypal in nature, and that is VERY COOL. I like the way he's striding out towards the viewer; it adds to the threat, especially when you see the blood-spatters he's left behind, and the tattered, stained maps and plans that suggest worlds destroyed. Makes you want to get out of his way...fast.
