Hey man, you guys are pretty good, but you need to drop the 270 out of the tail/noseslide unless you're going faster and power through that last 45 degrees. It doesn't look good unless you ride away tic-tac free. Loosen up the trucks.
Also, that's cool that your friend is in a band, but don't use them as the music unless they have a record deal or at least a little production value. It kinda has that awkward "I'm 14 and feeling up a girl behind the bleachers for the first time" kind of vibe. You know, the kind of music you listen to when the girl dumps you and you feel sorry for yourself listening to it alone in your room, thinking life will never be the same and how many people would miss you if you killed yourself. I had to mute the sound after about 60 seconds.
Lastly, don't make a fool of yourselves in front of middle aged black folks. It just backs up the stereotype that all white folks are goofy and awkward.
