She moves well, but consider adjusting your spine controls to give her more bob in her step as the weight of her body comes downwards with each step. As right now, she looks like she has a backbrace. Your flip also appears to slightly clip into itself. I would recommend planning each important frame of the animation and posing it to look accurate, then build your in-between frames to fit those poses.
