Could do with a lot of work
The main issue with this flash is the voicing. The sound quality is horrendous, you need to get your hands on some microphones with better quality.
Also, the character graphics are okay, so are the drawings in general, but the animations are extremely stiff and unnatural, which is something you should focus on fixing. After that you can focus on your graphics, find your own style for the show and keep it, only with minor edits all along.
Good luck.
