Holy crap, that last page! She doesn't even look human all bent over like that. I don't know why, but she somehow she reminds me of the raptors from Jurassic Park.....
@AbysalMonkey, I know, Her pose isn't weird, and perfect. The weird is the background behind it.
The background stay flat when the camera view in front, it should more compex than flat
its should more like this, to correct visual optic and balance the character, example :
I agree that is is the background/framing that makes that pose look more off. It is actually quiet a cool pose considering even some experienced artists have trouble with proportions when there is very little torso to gauge from.
