Not bad for a first submission
I liked your lip-syncing in particular, but the movie seemed to cut off prematurely as it looked like the character in green was going to say something back at the end. One other thing, a preloader is often very helpful to viewers and can often help your score over not having one. I would advise using one for future projects. You've got a good start to your flash-making experience and you seem to have a knack for it. I look forward to see you improve on what you already have.
Best wishes
