A lot of potential
However maybe if you had made the Cons a bit more dynamic... like Screamer would be his smirkier-than-thou self, Megatron would be a total and complete badass, and Soundwave would be the menacing shadow of Megatron.
I mean it was good, but it could have been better. I can deal with the voices (because thats just what a flash by Soundwave aughta sound like ;) ) but there could have been more effects besides the flash itself.
So a 10 for animation and cute plot. But a 7 all in all since it didn't suck the audience in enough until they figure out the punch line in the end.
Still make more flash please! Your animation is incredible :)
