I feel like the walk's too stiff. Chun Li has a bit of arm movement for both arms, so it looks unnatural for the sword arm to not move at all.
Run's torso is also stiff. If her walking has that much jiggle, her running should have more, or at least some. Arm's should also move at least a tiny bit. Her hair should flow, not stutter. Strider from MVC's scarf might help with hair, as it flows well.
Her hair kind of grows. It's really noticeable in the attack animations. From the size change, it looks like her ponytail is leaning heavily to one side, then becomes centered when she turns.
