Groovy!
Really good job! You have improved in some of your script writing from previous animations, although there is still room for improvement - proberly just due to translation and so forth, i just found myself having to go over what was said a second time to get some of the jokes.
The plot was also a bit thin in this one in comparison to the other episodes i thought, seemed to be more or less one long training montage, which isn't a bad thing, it's just i was slightly expecting a bit more development in the plot this episode. But i enjoyed all of the details you put into the animation, along with the characters, and i look forward to the next episode!
