Damn that was really good. Had a good pace to keep my attention. Shots that are too long can come off as boring; this was not.
I was honestly expecting a narration, glad there wasn't though as many come off as cheesy. The music choice was really good too.
The only critique I can really think of as far as something I would've changed would be that I would only add the audio if the quality was better. Unfortunately due to the waterproof needs, Gopros suck for audio. I liked the feel the woohoo! gave, but the typical sound of it coming through a Gopro took me out of it a little. It might sound picky or whatever but that's my two cents, and I'm not saying you need to change it, maybe others like it.
Overall though I really liked it. You just took my girlfriend on a rollercoaster of emotions though as she's too scared to do most any of this hahahaha
