Yuck
~ Animation/Graphics ~
They weren't terrible, but there was so much room for improvement. I suggest perhaps thinking about adding some colors into backgrounds and your characters, making much more detailed graphics of your characters, making much more detailed backgrounds with objects, adding more complicated animations since yours consisted of mostly very simple things, etc..
It may be more work, but it will make your movies so much better.
~ Story/Content ~
Ah, never liked the joke, but didn't let my opinion get in the way of the score. Could have been much better presented if it had better animation. Poor graphics and animation really brought the content of the submission down. Very over done, but again like I said I didn't let any of that effect the score I gave you.
~ Audio ~
This is what the yuck was for in my title. Wow, the quality of the voices really need to be improved. Very hard to understand and also took a lot away from the content of the submission. Perhaps back away from the mic a little bit. Almost sounded like you were spitting in it.
~ Overall ~
The content of the flash is suffering from poor graphics and very poor audio. I'd work on the audio before anything else though. Keep working and don't give up.
