I'll give you my 2 cents, the filming was really shaky, were you using a stabilizer? That should be easy to fix with a little practice. Secondly, a lot of shots were over or underexposed, and in addition some whites were super blue and some were super orange. So just play around with the 3 way color corrector in your editor. Some shots were slightly out of focus, just pay more attention to that while your filming, or even just cut those shots. Lastly, there was only like maybe one non skiing shot, I would try and throw a few more in there just to make the edit flow better and not go to fast.
