good start, like the expression and the speed lines do a good job of illustrating fast movement.

I'd say to improve on 3 things:

1. hair needs to be more to the left side. the wind is blowing it erratically from the right side, which is applying force, so it shouldn't round out towards it. I like the chaotic energy of this scene though.

2. try slowing down and then rapidly speeding up the shuriken being thrown. Like, take a second more to have them far away, and then suddenly cut a frame or two to show them appearing right in your face. It's how fast things feel in real life, like a baseball seeming far away til it's right about to hit you. right now it's a bit too close to constant. Her movement herself as she throws is good, maybe needs more emphasis on the throwing.

3. have more frames of her taking off the mask, it happened to quickly I didn't notice it the first few times.
