Nice job... good for such rushed work ^^
i like it its pretty good, the animation is great and i see that you used pivots for the limps
if you are gonna use pivots only apply them to major joints on legs, arms and heads make sure that the armor is steady and attacched to the arms so it doesn't look so bouncy
besides that the music choice and syncing could have been a bit better but that takes practice in my opinion
you've improved much since your first flashes and show much potential, just try and get the hang of it ^^
