Skiing: Im gonna be blunt here, you didn't do a single trick in this edit that impressed me.
Filming: most of the filming was good. Stable, good tracking. No problems here.
Editing: Too many fillers for not enough skiing. Your cuts in the middle of tricks are too quick, you need to give wiggle room on the end of each clip so the viewers eye can catch up. Also, you do not need to be editing it to be super wide, if you aren't putting out impressive content people just get annoyed with the widescreen.
Final point: Fundamentally, the actual producing was sound. Don't worry about filming, give yourself time to improve as a skier and take the camera back out when you have something decent to point it at.
