You did well man. Next time you will do even better! :)
Animating could use a lot more work. The scene with the chopper was pretty good tho, except the tail rotor was glitching after every rotation. You could also work on the quality by taking your time to make each scene as high-def as possible so it looks better, whether you're just watching a playback or trying to edit it again. The music worked quite well with the images and is actually why I'm reviewing your work. I can't find the name of the first piece, do you remember what it's called?
tl;dr, You can do better! Work hard! I'd love to see your next improved piece.
I understand you relize your mistakes with this animation. Just improve on the movement, and art. And then you should be fine.
I thought that it was a very zombified experience and i would like this Animator to Post more he is Very good
