Take your time
I fear that this animation was produced with the idea of fulfilling the entire story rather than producing a good quality flash.
Take your time, you could have easily turned it into two or three 30 second episodes of well drawn, well sounding and well produced animation.
It baffles me as to why at the end you would use text and straight lines when the style of the rest of the film is hand drawn and sketchy.
I say try again. If this flash survives the Blam, then attempt to remake it, or a sequel with some TLC, with sound, fluid action and some slower dialogue!
Keep working hard, you definitely have a style that could make a good short animation.
