Cosmos Chaos Very Good!
Animation= Very smooth but a bit dodgy here and there(When you focused on the the guy on the jet boots, it looked a bit weird to me, the swimming aswell didn't look right, but on the other hand, when the dragon thing flew over the hills, that looked great!)
Drawings= Mostly good, but sometimes the characters limbs looked a bit odd, out of shape. I think you just need to spend more time on getting the characters proportions right.
Overall very good!
P.S. Please don't take criticisms the wrong way, I'm only trying help you build upon your skills :D
