Pretty nice.
The next one should be longer. And I know you said that. And also, I would enjoy better graphics. It looked a bit sloppy with the lines sticking out in places where they don't need to. And maybe adding just 1 more shade would make them pretty appealing! So just consider that in your next animation.
There were some pretty good parts though. Frame rate was more than I expected when I saw the rating. As well as how the audio was awesome. You put in some nice sounds. So, great animation, just needed some more length and visual quality. So, good luck on your next animation, and nice job.
