Don't be so hard on yourself, it wasn't bad at all.
First, I congratulate you on actually being able to make a Star Wars film that not only lacks the "crawling text" intro, but also has more video time than title time. That is unfortunately getting all too rare nowadays, so it's great to find those things missing here.
The biggest problem is the mouth animation, as is often said, unless it is extremely good, (Nick Durron's "Zombie" films, "Unrenewable" and "Foster the People - Houdini (in LEGO)") it's better to leave the mouth animation out.
(I'm sending you more info on that subject in a PM to keep this review down to a decent size.)
While some of the jokes were overdone or so-so, the execution and timing was great.
And if you had slightly better (And original) material, you would have had an awesome script.

That being said, "Band-aid," "Suicide corps" and "Lack of space" were good lines, and very funny.
The animation was choppy in most places, the figures looked like they were bumped several times, and there was some light flicker, but I think it was still pretty good. You've nailed one of the harder aspects, (Comedic timing) so just work on the animation, and getting away from overused memes, and you'll be quite the animator.
