A thing I really noticed were the super wide shots (I assume they are GoPro shots?) where the skiers/boarders jump over the camera are very dark and not really warm. When the you start using your footage from the other camera again at 1:36 it's a whole different video almost. Warm, rich colors, sunny etc. Maybe try to match them a bit better color-wise next time.
And also, maybe take a look at the exposure a bit. For example the shot at 0:41, take a look at the sky. Little bit overexposed, you could put a little bit more blacks in a shot like that.
Last thing:
The first shot: the guy in the yellow was a bit OOF and his shirt was REALLY blown out.
Overall it was a fun edit, especially the laughing guy at the beginning (0:12) was cool, looked like you guys had a lot of fun, and that's what it's all about, init? Keep it up!
