Something i noticed.
I've watched three of your animation in the portal when they were freshly submitted. I've noticed when the animation finishes and start back at the play screen, you music/sounds over lap. I don't know what animating or sound program you have, but learn to cut the audio to where it won't continue playing or search a tutorial that will help you find someway to make it stop playing at the end.
Either ways, i liked it. Your animations are good.
