No one cares about people who cant take criticism. Righty.. now i got it all out my system the constructive criticism from moi. Helmets are needed. (if enough people tell you now.. then maybe you will get pissed off enough to wear them) Take a look at your gear ratios, the one guys looks properly odd i cant tell whether its too hard or just too easy. Also you need to sort out your brakes, buy some plaz pads and grind your rims. Slow yourselves down when you come up to drops some of it looked like the bike were controlling you and not you controlling the bike. Its ok to have the camera sat on a wall close for a shot.. but i wouldnt say more than 2. Its best to stand away and get everything in shot, when you get better at editing then you can start working with close ups and angles better.
