I like it.
I do video for a living...not ski videos though, sadly!
The first rule of video is tell a story. You are doing that and I applaud your efforts to capture the experience. You play around with different angles and camera positions which is also important. When you shoot your video think of the edit: what shots do I need to tell this story?
Another important aspect was mentioned earlier - communicate to your target audience. You were basically making a home movie of your ski trip for yourself and your friends so good job of keeping your target audience in mind.
The only critical comment I will make is that you tend to hang onto some of the shots too long and perhaps put a few too many in. This is extremely common and is the hardest part of editing - leaving stuff out. I have a love hate relationship with good footage: It is great to have plenty of it but makes it so much harder to decide what to use and what not to use.
More thoughts. Pacing is crucial. Cutting to the music helps as well. The shot where you wipe out (around :28 in) would be better placed around :41 in where the music gets quiet and you have a kind of nice but not super interesting shot.
Critiquing videos used to be a large part of my job and I am now off for the day.
