Animation is great but I don't see how she's managing to hold that position. Her center is going way backwards. Way too much bodyweight is distributed backwards, and it's not like those wings are helping.
There's some nuance here I have a hard time conveying. I get the feeling someone asked her to do this because he couldn't bother to train. Hence the 'ne?' ending part.
And related to http://danbooru.me/post/show/10287 Which I cannot see(requires a privileged account), which is why I uploaded this in the first place... Sorry if I screwed up.
