I didn't think it was too bad.
You reminded me how terrible student actors are, i have to shoot my own short film for my HSC later in this year, and I'm starting to consider hiring a professional.
Anyway, I'd work on your sound, I'm assuming that you didn't use a boom mic, heck, even a hand held mic, tied to a broom and someone to hold it will work.
I'm assuming that your actors work for free, and as such really aren't that dedicated to learning the script and giving in a well rehearsed performance, try and get them enthusiastic, offer things such as : Booze, Sex, Porno, Fire Crackers, etc ..
If you wanna be a smartass, when Jeph changes his style in the comic, you should change the actors.
