I also think it needs more sound. This way, ti felt very awkward, and the crude, low-detail art style/animation didn't help. The fact that the dino couldn't reach his gun was pretty funny, though ultimately this feels unsatisfying, it just sorta happens. The meteor thing was pretty good, but, again, just sorta happens. I know you don't have a lot of time to make these, but try adding sounds and having a more satisfying story in the future.
