I've actually not seen The Last Airbender, though this art is pretty good regardless. The blurring is pretty strong, and the pose and framing is cool and actiony. The streams of water behind her seem a little too much like cloth or something, though they look great in the front. The water drops look a bit out of place, too, specifically the ones on the left half of the picture. There's that one tiny wave that looks a bit too simple. Still a pretty cool piece overall with a nice sense of action.
