It was pretty nice
I liked this a lot because of the animation. It's actually kind of strange, because the animation of the mammoths seemed pretty detailed in comparison to, say, the caveman. It was interesting as I was thinking about how the caveman was going to defeat that alien creature. It was a pretty weird cartoon, but luckily I'm a big fan of weird things. The music was pretty nice, if a little generic. It's nice that you listed your influences and all of the stuff that went into making this neat little cartoon.
