Cool video
I've got heaps of tips for you guys though as a team
First off- the camera is obviously shitty
Since you guys are a team and seem to ride together alot and are probably friends INVEST in a better camera TOGETHER, it will really help out in the end, or if one of your guys' birthday is coming up have their parents buy a nice camera, i'd say invest in a panasonic gs-320

I think with all you guys you could definately afford that after a bit of savings and are serious.
Second- Work on your filming! When and IF you get a better camera, definately work on utilizing it to it's full potential and learn how to use it

read that it will seriously help you.
Third- As for riding, get your basics down, whips bars and spins and fakies and all that. make sure you have them clean and every try and you'll progress so much faster from there when you learn combos and everything
