The quality is fine, but I think if the animation was more movement oriented, like a running vault or a cool spin attack, it would have served better in regards to how the rig can operate, as well as how your animation skills are doing. Showing fundamentals through more complex movements.
The hair dynamics/animation should be toned down a bit. That hair is whipping back and forth a bit too much and takes away aesthetically.
Personal note ; I'd love to see more design for the character. What's her story? What's her purpose? I don't get much from her awesome stilettos and sword :P But that's just me being nit picky.
Thanks for sharing!
