Kick ass animation! Maybe i'm too slow on the joke though and don't get it..... ah well.

You've got potential fo sho. Just keep going at it, take some more time, your frame rate n shit looks pretty good. If you're going for shakey lines style best not to make them too messy so I know what i'm seeing. For giving credit where credit is due, when you're publishing your video there should be acknowledgement tabs or something, you can credit where you found your shit as well as music and even writing them down in your description. Giving credit to the musicians, sound fx people or whatever is nothing to skimp out on since people are insane about that shit. (Plus non credited copyrighted shit will get your vid taken down in most cases, all it takes is for someone to report the video saying "I MADE THAT SHIT THEY STOLE IT FROM ME" and some proof and it will be removed)

Not too bad, definitely keeping going and learning growing, you have tons of potential. The computer mouthing "dafuq" was probably the best part of the whole thing.
