I understand you're young and talented, but I would stray away from putting down the years you've been involved in each discipline (cinematography/photography). Clients won't appreciate hyperbole; directing/producing a short film at 18 is astounding, but directing/producing/shooting a movie at 14 or 13 as you say is simply not a reality.
amending this will show more professionalism in my opinion.
Get rid of the music, no ifs ands or buts. Someone in any professional setting will close the window the second sound comes out, trust me.
Although I highly recommend you drop the music, if there was a reason to have music playing on every page, the only viable solution would be to have it in a pop-up. Even then many browser will just block it.
Yes, so your website then tells us that you have been making/filming/directing movies since you were 13, and you've been a photographer since you were 14.
Nowadays is safe to assume that without the prefix "amateur", one is to assume professional; and, though many try to call themselves as such far too soon, a true, freelance photographer/videographer can't morally call him/herself one until he has reached a certain level.
Clients will know that a 13 year old is not a cinematographer and might get the impression that if you thought you were then, you still think the same now. Either include information that supports your past (testimonials, resume for download, demo reel, etc.) or just change it to focus on now.
