Casting help needed!

Halp! I need to figure out a good "played by" for Artemis from Young Justice. That is, a real person who could convincingly be the same person as is drawn for the animated show.

Here are the facts:

- 15-16 year old female
- Long blonde hair, dark brown eyes
- Half unspecified-Asian, half blonde American
- Short-to-middling height, say 5'4"-ish
- Athletic (she's an archer with a lot of gymnastic/acrobatic and martial arts ability)

And here are pictures:

Any suggestions?
