A couple things I noticed:
1. Way too many out of focus shots got a little annoying
2. Some shaky shots, especially in the beginning. I've never filmed off a boat but I guess it's probably hard to stabilize well.
3. The water ripple effect is a little amateur in my opinion
I liked the shots at the end with the close up of the wake boarder, made me feel like I was in the water watching. I enjoyed it and will look forward to seeing some more.
