Okay, a couple things, but first, I don't want to come off harsh, so take everything I say with a grain of salt.
You need to either a) white balance, or b) color correct. It looked like god drenched the mountain in pee.
You have great content. Your friends (and you?) are really good. What you need to do is get out of the mentality that pointing a camera at good skiing, putting it on the computer, slowing it down and slapping it to music will make a good edit. This is one of the biggest hurdles in the learning curve of video because it involves preplanning, ie envisioning your shots before you take them. Don't just stand next to the rail and film your buddies, because quite honestly that's boring. Get some movement (and not just followcam movement). There's a reason that eheath and DTF are producing such high rated edits, and let me clue you in, its not just the editing or the fact that they have nice cameras...its the creative and artistic way they use their cameras, regardless of who they're filming or what camera they're working with.
In addition, I realized that your editing was not really much more than tossing the clips to the music and slowing some of them down. The cuts nor landings matched the music; their was no cohesion. You left some good audio in, which added depth to the video, and that I really liked. However, I think there's definitely room for improvement, and it could be just as simple as taking your time and being more attentive to finer details.
Don't feel like you have to finish the edit as soon as you can after you go skiing. If you want to produce something truly artful, it takes time. Think of it like writing a paper; most of us write our papers the night before they're do, but does that really result in a good product? A good paper goes through many drafts, many revisions, and is critiqued a few times before it is ever printed. Take your time. Think about the cohesion of what you're putting together. Think about what shots you leave in, and what shots you pull out. Think about shot length and varying it. Think about transitions. Think about the overall phrasing of the video. Surprisingly, papers and videos have a lot in common; it's my favorite analogy to help describe the work.
You're on the right track, and practice will only help you. I know I've got a lot of cons in this review and not many pros, but what you need to take away from this is that the sky is the limit. There is so much you (and we all) can do to improve. So keep practicing, trying new things, and refining your skill. You'll be producing bangers soon enough.
Hope this helps, cheers.
