Hmm... well this isn't bad I guess. Most of this drawing overall has that anime feel to it, which is most likely what you wanted given your comments in the description. The eyes do appear out of line with one another, this probably could be fixed either by realigning them, or you could add some additional facial details. I dislike how the eyes seem to have been added at the last minute, they don't 'flow' very well with the rest of this, and don't seem very attached. I'm a bit confused by her hair, I'm not sure if it is her hair, or some sort of headwear cloth. Either way, I think it looks too bulky. If this is hair, it should look like it has individual strands, of course don't draw it as such the idea is just to make it apppear that way. If these are indeed 'ribbons', then it isn't so bad, still more depth and shading could add more character to this sketch.
A few parts of her anatomy have been unrealistically portrayed. Her right arm is at too much of an angle, I doubt this position would be humanly possible. The elbow should be visible if you want to make this look correct. Her left arm is in possible position though. But both of her arms seem too 'wobbily', I think you overused the curves a bit here. As a whole, the upper body seems to be at a 'tilt' to her right side as well. The best part of this sketch is probably the fans, very nice looking, they seem to follow a distinct pattern. The only thing you should work on in that area are the actual blades.
The rest of her body looks pretty anime-ish in form, so I am sure you achieved your goal there. As mentioned though, her left foot should not be at this position, her body would have to be turned with the foot. The legs, while a bit long, aren't 'wobbily' like the arms are, I can identify the joints here. The costume is traditional, seems well drawn. Keep working with it, this is a nice start.
