I can see what you're going for, and I actually dig it a lot. It just needs a little work. I little more focus on framing, proximity to subjects, etc, and your shots will be there. I really liked your pans on the rails, they worked for me. Nice job.
I'd get rid of the talking. It doesn't do much for me. I think the first kid is trying to be sarcastic and in fact complement the other kid's skiing, but it just doesn't work. Get rid of it and let the skiing speak for itself. Same for the other kid. If anything, for me, it brings down the vibe of the edit. The song is so happy, so upbeat, and you have these kids talking shit about each other. I get that it's supposed to be funny but it's just not working, cut that shit.
The "moire" that you're seeing is motion blur. Pay attention to your shutter, frame rate, etc, and do some searches on here or on Google to help out with that.
One thing that I think would really apply well here is shot length. Varying shot length keeps the viewer stimulated and engaged, just like varying sentence length in a paper keeps the reader moving through the material. In essence, the short shots wake up the viewer and can prepare them to make it through the longer ones. In your edit, all the shots are kinda slowed down and they're all the same length. Change that! Switch it up! Employ different styles of filming and visual video transitions to chop up the monotony. If you do that, two minutes will fly by instead of drag by.
A few more things, a little more specific.
0:04 seconds: look at your horizon line.
0:21 seconds: get that kid out of the shadows, half his face is shrouded.
1:51 - nice cut, I've always been partial to edits like that. Ideas and creative thinking like that will serve you well in the future as you refine your skill.
You're on the right track, but attention to small details will help you a lot.
