ill say this, the intro was pretty fucking cool. you just need to work on these:
Replays, (try it out with the replays that toribash came with installed in it)
Shaders (but thats a computer problem, I feel your pain because I use to not be able to have shaders too...
You really should use
Bezcam, or the keyframe system implemented in the game already for replay recording. And try to find a different kind of recording software, fraps puts that gay logo on top and it annoys everyone lol.
Sync: Watch a lot of videos that are made by veteran video makers, and you will relize how much sync can make a video epic.
Effects: just add effects, and be clever with your transitions.
Hope this helped.
