''Bet you can't do this!''

A lot of people asked for themed digital art for this month, so here's Nim hanging upside-down. 
This was kind of more of an experiment (surprise, it's me) type thing. I'm not really the best at drawing humans or birds, or any other pose other than ''Sitting facing forward'', so I tried to doing something I find really hard.
This is still a work in progress, I plan to add feathers, talons (she's hanging from her talons), a background as well as fixing and adding some details.
I'd be really helpful if you could give me a critique on what to improve on, because I'd really like to make this not awful, honest!

Seriously though, even a little criticism wouldn't hurt, even if it's just in a comment, I'd love to see what you think I should work on next.
