10/10 for animation. It ain't only very good, but also really really original. The voices are also outstanding for this type of plot. I just see some points where there should have been af few changes in dialoge.
Per example, when the rainbow was trying to interrupt the cloud he should just, at some point, have gotten really angered and shouted 'WHO THE FUCK TOLD YOU THIS YOU FART!?!'. And that entire part of him trying to interrupt the coulda been just a few lines shorter. Overall I can say that the voices should on certain moments have been more expressive, plus the animation should have been more compact. Work on this, because combined with this exceptional style of animation it will be excellent.
