BTW, I enjoyed your promotional piece.
(I realize the goal of the piece and the target audience)
I think its great that rather than focusing on traditional sports or wasting your time with superficial activities you are paddling at a young age and learning how to combine your interest in film with your passion for paddling.
Being a whitewater filmmaker is a thankless endeavor really but the reason to do it is because you love it. Accepting valid feedback is important but don't take it personally, keep following your dreams my friend and seeing the world. We need talented young people like you to transform our culture and save our rivers.
