Time is one heavy factor in animation.
The other being skill, and the creative drive to force yourself into displaying your story through your characters and expression.
It's a test, so of course it's not going to showcase you at your best, however I believe you could have kept this in the 'dumping grounds' section of NG.
People are bound to give negative feedback, not to be mean, but hopefully to guide you to success in improving your craft - but if you don't have time as you say, then how can you devote further time into a final, complete package?
Priorities. I'd say, drop the videogames for a full month, do tutorials, stop hanging with friends just for a few days, or weeks, and see what kind of work comes out of it. I'd be willing to bet you'd be happier with the results once you see them.
Good luck with the future, SharkCartoons.
