Best stuff wasn't yours.
'Thanks to AlmightyHans for his assistance with character design in the film'
assistance?! The best drawn characters in their were 100% drawn by Hans. It's ok to use his art, but give him way more credit!
The animation was pretty bad. There was a lot of artwork, but most stuff was badly drawn and the animation was even worse. I always like a song that was made by the animator himself, even though this one wasn't really good (voices not loud enough, sounding dull)
but, you did seem to put quite some effort in this and I think that's always a good thing. I bet your next animation is gonna be much better. Use your own stuff though.
