The Good: The music set the mood.
What needs work: Slow down the frame rate. You couldn't see half of the space battle because it zoomed by. Also, make the ships for each race be unique. If they look the same, it's hard to know who is who. Also, make the battles more in depth. One shot shouldn't be all it takes to kill a ship or a person. Dodging and what not should be involved and make fighters spew out for several rapid waves to kill the motherships. You didn't know how many ships were chasing the first so after that one died and the guy was like, "one down, we don't need additional ships" you had no idea how many were after "one down".
Also, make your style of speech more military sounding. Instead of, "Send out the fighters, now" make it something like, "Launch the Fighters, ASAP"
All in all, I liked it and I want to see more, but you need to work on the details a bit.
I personally like stick figure movies so I say keep them.
