Every good animator is born as a baby.

For a first animation, There is a great attention to detail, however I do enjoy the occasional taco, However, you can tell there's a varying amount of effort which is fairly easy to spot, regardless of whether you care or not. The space segment has some great parts, the Mario and Yoshi animation, the DBZ guys, but then there's the others which im being a lazy ass and not typing out that have less animation, etc etc. You get it. Bitches. Either way, nitpicking on stuff you already know can be improved on, and It'll be nice to see even more. You have good timing and pacing, and your art is soft enough you can actually look at it, which is like 8% of the submissions here, which is good. Hope you get even better!
