Not bad, nice critique
I like how you did an animation on the iraq war *I'm assuming here from the characters* but some things need to be changed.
A. Your characters bob up and down, to represent breathing, yet they bob too much. It looks like they are wheezing when they are standing still, are they asthmatics? lol
B. Your snipers need to be a little more realistic. They are always covered, somehow, and they still themselves before a shot.
C. Your helicopter animation was a little...stale. You did well with the men *assuming here, nothing against females* but the helicopter was very...blocky. The stairs that dropped, just seemed to appear.
Great job so far though, keep it up!
