not bad, can improve.
Ok, a few things. First, the animation. Some frames its fluid, others its choppy. One can never really catch the flow to the movie. Also, if your going to make the wind make some guys shirt move, might be wise to do the same with his hair...especially when its blowing in the wind just a few moments later.
Graphics are pretty good, but without full blown animating them, they look stale.
The story..i'm sure the comic books are great, but people (like myself) who have not read them would like to know a bit more about the story. 2 guys fighting over a chick who looked like she was about to be OFF'd then having dragons come out of everyone kinda threw me for a curve.
Sound. You lose points here. You cannot put a highly recognizable video game song(Halo) for your background. First off, when I hear the halo sound, i think of master cheif going nuts on aliens, not sword swinging people who turn into dragons. So please be a bit more original here. If you cannot locate something original, check the audio segment here on newgrounds.
This has a lot of potential to be very kick ass, but need to make sure the foundation is set before proceeding.
