Well your music selection wasn't THAT horrible. Actually I've seen Fort Minor used a lot in videos trying to establish some cred in what ever it is that they do (and that song in particular). One thing you may want to consider though- is using the radio edit version of this song so you can avoid the F bomb being dropped.
The video shots are not framed in a way that I found pleasing. Bust or crotch shots work well enough, but there wasn't enough full body or face shots. I couldn't connect with any of the performers emotionally. It was just a bunch of hands being thrown up in my face juggling cards.
I don't understand the vs concept in this video. I understand that you're trying to do a competition between three people, sort of a two on one thing, but there isn't any kind of criteria to define what the audience should be looking for. The average layman doesn't know a thing about cardistry so I'm not sure they'd be able to say with any credit that X person clearly won because of Y things. Maybe some kind of commentary track following the video, or subtitles explaining things that are "cool", or hard but executed beautifully would help solve this better. Also maybe at the end, instead of letting people decide for themselves why don't you just say who you thought won?
I wish you the best, and by all means keep the videos coming. Everyone you do you'll learn more, and get better. Keep it up!
