some problems
first off, you need to work on the animation:
it was anime style, which means you were lazy and used flashing lights and still frames to create motion. anime style is good, as long as you have half still with lighting and half actual animated sequences.
second, even though it kind of goes with the first, you need to work on the jumping. they were just kind of floating shapes with curved trajectories.
third the music. the base was too loud and made the sound unbalanced and blagty (bla-tee, for those of you who cant pronounce it). I turned my speakers down and didn't much of any music.
ok overall
(P.S. the blood trickling from the mouth does not happen in real life. the waist being pierced will not cause blood to come out of you mouth , contrary to common beliefs based on other movies who do not know their anatomy and biology.)
(P.S.S. Before you reply saying that I shouldn't say some of those things because i haven't made my own movie. I have fooled around with flash for about 4 months now and i know its hard. In fact, im working on a music video right now and i hope to release it within 3 or 4 months from now [based on my schedule])
I hope i didn't offend you with my critisism, it is meant to be constructive
