Huvvah, that’s an eye-bender. I’m not particularly well-versed in these kinds of things, but I got this instinctive notion that it’d probably be grander and more impressive if it was, like… well, a really, really big thing, built up of a whole bunch of bodies. This one I feel is a bit… well… it feels a bit too small, too round, too… well, not very menacingly demon-y, really. So’s my impression, anyhow. Perhaps you’d prefer to keep it on this scale; I just think it’d be wicked to see something… dragon-y* built up out of a hundred different bodies all twisted and deformed together!
Otherwise, if keeping with this sorta scale, well, maybe it’d get more spiffy were one to add all sorts of ornaments or armour to the body. This being, after all, a demon lord.
*I’ve got a thing for putting -y:s after everything. I call it being y-y.
