First things first, it is actually a good edit, but there are some things I would like to go into detail with.
1. I see you have used the Warp Stabilizer in Premiere Pro quite often. Now, the Warp Stabilizer is a genius tool for any filmmaker, but make sure to go through every clip after using it. Some of the clips in this edit shows clear traces of Warp Stabilization(it looks like you're zooming in and out real fast). Try to change the settings in the Warp Stabilizer to find the perfect balance for each clip.
2. Try to experiment more with color grading. Some of the clips look rather good, whilst some look a bit bleached out.
3. Shoot the same trick from different angles. There is always room for B-footage. For instance, the back-flip shots: If the skier could have done that trick two, maybe even three times, you would have gotten the chance to shoot from different angles.
Could probably have gone into greater detail about many other things, but this time I choose not to. As I said, it is a good edit(not a bad one at least), and it flows good. Personally, I would have chosen a different song, but that is of course up to the filmmaker. Keep up the good work!
