What should my OC's Patronus be?

Here are her traits:
- Intelligent/studious (she's a Ravenclaw and she's rather obsessed with academic success)
- Socially awkward (painfully shy; barely able to talk to most people)
- Clumsy (she runs into things all the time and is forever falling down and dropping things)
- Artsy (but more interested in viewing art than creating it; she has no confidence in her artistic ability)
- Theatrical (kind of a drama club geek, despite Hogwarts's lack of a drama club)
- Rule-oriented (worse than Hermione, though not quite as horrible as Percy)
- Perfectionistic (she's a constant critic of both herself and those around her, much to everyone else's chagrin)
- Stubborn
- Easily irritated
- Dreadfully lacking in self-esteem

Physically, she's sort of small and, like, skitter-y (if that makes any sense). And, as I mentioned before, dead clumsy.

Hope the information helps! I'd appreciate as many ideas as you guys can give me! Thanks in advance!
