Not bad... not good either...
Those flash effects really clashed with the video footage. If'n you do this kind of stuff again, I'd suggest adding a transparency to the lasers to make them more realistic. And those damned stick men just killed it.
And I'm running a 1.5 Ghz Pentium 4 system and the sounds was way off. I seriously doubt that it is the viewer's machine's fault, but I'm sure using streaming audio would help.
Hope that was helpful.
