animator vs. animation
your work reminds me of noogai's animator vs. animation series. perhaps you had been inspired by the series? i recommend you check out his Flashes, if you have not already. it is only a recommendation, so do so if you wish.
overall, i enjoyed your animation. i felt it was too slow-paced. action should be fast, it should be quick, it should hit you like a train. the sound effects were enjoyable. your own sound effects? i like that.
for your first Flash, this is pretty good. i wish you luck in your future endeavors. cheers!
