Seriously man sort out the audio, not only is it the worst possible quality, but it cuts out for a fraction of a second every second, I was gonna just leave but I like you so I just muted yours and listened with a decent version.
Firstly tell your friend to stop reverting, he's not going to get any better at skiing switch if he's always trying to get out of it. And it doesn't look great.
I love the song, but it's not really the right speed for your skiing, as you were going pretty fast on some of the jumps and it's just a slow song.
1:11 was out of place.
Nice edit though, like people said kinda shaky is all, although not having used a glidecam I don't know how difficult it is. Seems good to me. Oh and if you're using the slide transition don't use it all the time, and there was a bar at the top on the first one.
