A few tips...
A few annoyances I noticed involved laziness. when looking from a human-eye view, the people don't always have to be facing the camera, it would be nice to see side views of people's faces. Also, maybe record some of your own sounds. Those counterstrike phrases are getting old on NG. Also make unique characters. you had one or two different characters, but that is not enough. Too many of the same people. And one last thing, more animation... IE: Legs moving when running, etc...
Hone your skills.
