Not sure what the purpose is
It seems like all you did was copy the idea of Bungie's Halo 3 Trailer. However, the graphics are very nicely done. My only complaint is that Masterchief was a little messed up with all of those black outlines. If oyu plan to make a series out of this, I would try to clean the MC up a little.
Also, for next time, if you are going to make a trailer of some kind, you should try to be more original and give some kind of idea of what your movie's about.
