Think I saw this one a while ago, it's a really nice piece, and solid animation. only criticism (constructive) is that the sword(?) she's holding in her right hand looks a little bit off..

 I really can't help liking her shorts especially, as well as the animation here, good work c:

Very cool! I like details like her glasses and kneepad.

 So hot, well pixeled and animated. :]

Enough frames for my taste, but

- the feet should not rotate
- the hair movement is unatural, and could make the bouncing much more cool if done properly

oh, and very sexy ;)

 great shading/fluidity, though something about the kinda of rotation of her bounce seems a bit unnatural/robotic, like it needs a new more frames, or something needs to be offset.

 The way her right knee is twisting looks a little funny to me, but the animation is really good!

 Very nice and smooth animation!
