Lots of cool shots in there! Here are a few suggestions to try different next time:
1. Record some natural audio of the environment!
2. Record interviews with your friends! Ask them questions like where you are, why you are there and so on. Let the audience know what this video is all about. Sound is just as important as picture, so keep that in mind. More sound will help with one of your opening titles "Headphones Recommended". All you had was a song there... no natural audio, no voice track, nothing else... really we didn't really need to wear the headphones to listen to a song, but to hear more precise sounds then yes its necessary to wear headphones. Being an editor, I have headphones on for 8+ hours a day, so yes I did watch your video with a nice set of monitoring headphones. Enough with that rant... in all just loose that title unless there is some good quality audio in the final mix.
3. A lot of people were talking about your over use of light leaks or transitions. Personally I think transitions need to have some sort of meaning to them. Use them to help push your story forward, for instance change of scenes. Your at the cliff jumping area, use a light leak transition to transition into your camp site area. This not is only useful with light leaks, but any transition in general. All transitions should have some sort or meaning. We don't see crazy light leaks all throughout films in movies. We see transitions for passing of time, place, etc.
4. The shorter the better! No one wants to watch a 3:45 of you and your friends having fun. Yes, you and your friends may think its great, but you need to think about who the video is for. Who is your audience? I think with having just a music track, a 90 to 120 second video would be a much stronger video here. If you were to capture interviews or some sort of dialog and was able to tell a more compelling story then maybe the four minutes wouldn't seem so boring and long.
I hope you take all of these techniques into consideration when making your next video. Thanks and keep shooting!
