Mediocre.
This isn't a BAD flash, don't get me wrong. You say in the comments that you will disregard the reviews of those who haven't tried flash, and I have. I know how hard it is, and I would be proud of this piece of work. I'm not sure what it's based on, or any of the back-story. I am merely judging the work.
The voices were okay; good voice acting but bad quality. That is most likely just down to a bad microphone. The expressions were okay, but the hair seemed a bit stiff. The music did fit the piece well, but in time only; the mood didn't REALLY seem to match the music.
My main criticism is that the story is in bits. You have the boys at the blackboard. The boy with the blocks... eating him? Then him with no leg, and then the picture on fire.
This is NOT a bad piece of work, and with only two months of flash experience you could become a great animator. My advice to you is to keep working and watch other peoples work. If you learn to take different things from different works then you can put them together in your own style and improve the overall quality of your work.
Quick note: Please, as a request, do not be so hostile in your comments. It acts like a meeting point to trolls, and will only piss people off. Just ignore people who hate on your work.
