Have you ever seen some of George Miller's early work (aka Joji, Filthy Frank, etc)? It is a great example of just use your own voice/style and develop that. He got HUGE over time. Granted his later work would not be considered advertiser friendly but hey, he made it.
He has posted stuff from way back to what appears to have been his middle school days. I loved the knock-off of the Power Rangers type video he did from back then. To look at that and what he ended up with was interesting. I think if you check for Tempura Boyz under his DizastaMusic channel you will find it.
To think, that was made before Action Cameras...maybe even pre-digital cameras.
I believe he has evolved his style again and moved on to just music.
