it's really cool that he is getting into it... and he only seems 10-12 or so... good on him, and lucky you that he's also into it...
a suggestion for the next video, it would be good to see a little more emphasis on riding, and less on effects... i'd probably also go easy on illumination effect, as it tends to look a bit 80-ies, and i think audience always appreciates seeing the footage in it's natural form...
but otherwise, well done Marcus' son on the beat track and learning kiteboarding... get your dad to buy you a mac, it comes with a GarageBand program... it's another program you'd probably love for putting together cool beats...
p.s. Marcus, hopefully you'r next post/video is not gonna be: "Vomitron... it's a family thing..."
