Thank you so much for the extremely helpful critiques! I knew there was something off with the anatomy, but I hadn't been able to pinpoint it.
Wayuki, I never thought I'd live to say this, but you have anatomical issues.
Well, I don't consider myself an expert on anatomy by any means. I'm one of those silly people who learned to draw by looking at comics.

It's only fairly recently that I've tried to bring more realism into my work, and with a huge piece such as this, it really becomes apparent that I still have a long way to go. But that's also the very reason I'm taking on pieces like this... because I need to learn.
Anyway, looks like I have some major restructuring to do. I'll see what I can do about it tomorrow.

Where did you come from? 
From the dolling community. Bwahahaha.
EDIT:I adjusted the figure. Better?

I decided to keep the hand poses and the straight back leg, because I think changing them would be more of a hassle than it's worth. I wasn't really thinking "belly dancer" when I made it, anyway... more like "fantasy style enchantress".
