You definitely have some great shots in there, but you are lacking the main aspect to an edit, which is flow. Without transitions you can't establish the change in the shot. You also lack variation which is really key. It might not always be possible, but you could have a friend at the base of the cliff filming you as well, whether that is a helmet mount, or preferably a regular camcorder. It really smoothens up the edit, with a change in angle.
I really liked everything about the skiing in this though, you are very good. What program are you using to edit?
