Only two notes:
Great animation! Nice artwork! There are, however, two things I would like to point out.
First, sometimes the animation got a bit sloppy, for example when G.I.N.A. exits her space scooter thingy after docking it.
Second, if you have characters move their mouths like they're saying something, either let them have a voice (even if you can't hear what they say due to loud gunfire, you should at least hear something), or at least place some subtitles.
Other than that, great job, and I would love to see more of your work!
