Naruto or not... this is funny!

Animation: excellent job... it's smooth, well done and it creates its own style. You've obviously put efforst into it, and thus I commend you.
Art: This is where I really found myself attracted to your movie. The characters were taken from the original artists and pulled into a awesome world of adorableness. I loved the art, it never got boring, it was even and well executed the whole way through... wonderful and enjoyable.
Music: I laughed... seeing all these difference music references, from Disney (beauty and the beast) to Lady Gaga at the end... perfect selections!
Overall you did a marvelous job... bravo. The lengh wasn't even a problem... I actually wanted more!
