I like that background, it's creepy as, but I think it messes with the view. It seemed before she was upright, floating over the viewer, but now it seems like you're standing above her, looking down, and she's horizontal, or something, which isn't so scary.
Possibly my dirtiest/messiest crit ever, your stuff is beyond me:

Apologies for the butchery - intended just as a quick visualisation of what I mean.
Also, be careful with the dithering on your skull demon, he's looking a bit grainy, where he ought to be smooth/slimy.
