@00:12This was pretty interesting. Animation can be hard as all hell and you certainly seemed to have a grasp on it.
I kind of feel like the sound could have been a little more prominent, though. It almost came off as you typing in the background, rather than something intended. At least until you got to the point where the crystal (?) was chipping off.
Sachiko's face also comes off as a little broad and round. Maybe thin it out a bit around her cheeks, ears and hair?
