Well not bad at all.
Not a masterpiece, but for 3 weeks, this is as awesome as you can get.
I'd tap that..
The whole style of the animation, the colors, the theme, is great, not to mention the art itself. It really helps to convey the story, the art style, and the animation flows pretty well too. The soundtrack fits it's place also. Good on you Hikarian, and well done deadlyfishes. Nice piano score ya' got there.
Take it easy.
