I don't want to come off as harsh, but I feel I must be honest...
IT NEEDS WORK.... SIGNIFIGANT WORK.
For one, popping up "OWNED!"
right in the middle of the video is corny and lame... if you want a good promo video, don't EVER
For another thing, you need to do a much better job at editing your video.
What I mean is other than you pwning and the Linkin Park song playing in the background, theres no pizazz, as in there's nothing that really grabs the viewer's attention. One of your biggest mistakes is having just 1 long uncut, unedited peice of film playing the whole way through. The best thing to do is to have multiple clips, splitting apart those clips into highlights and cutting out all the dull moments, then mixing them back in together, MATCHING
(and I cannot stress this enough
) THE FLOW OF THE VIDEO TO THE MUSIC
I just have 3 words to leave you with when it comes to putting together music and video....
E V E R Y T H I N G
If you want to see an example of why this matters, watch this
video I made with the Half-Life 2 demo.
Best of luck to you dude!
