First one was better.
Drawings are good, as is the lighting and shading. However there is not real 3D feeling to it, as there should be one in a Halo Tribute. You know what I mean, at least make the guys turn around in battle like they should do against so many enemies.
The voice actors were a bit too bored for my taste, put more enthusiasm in it!
Oh by the way, how bout some better effects when firing a weapon? I know it's not in the sense of Halo, but it makes everything look cooler.
