Very nice.
This was an interesting film to watch. Clearly, someone's been playing some Metroid Prime lately, and it's always nice to see revamps of the old classic MM villians. If you're considering revising this first one (or perhaps still working on the next one), you might want to see if a couple of people will volunteer as voice actors for you. I know I'd readily lend my pipes if asked.
On another note, it's not "would of," it's "would have." Contractions that end in 've, though pronounced "of," are shortenings of have. If you aren't certain in the future, I'd recommend either looking it up or just using the contraction. Catching minor editorial details like that is the sort of commitment and attention to your work that separates the good Flash artists from the great ones.
