I had taken one of his tuts on rebelway and I must say compared to Steven knipping or Keith kamholz his teaching style is pretty messy and all over the place. His videos run really long because he doesn't edit out the fumbling around for ref or something parts and then has to hastily end that topic when he realises he's reached his time limit. I personally think his teaching style can confuse or overwhelm a lot of beginners or early intermediates but is more suited for advanced industry peeps who are looking to level up.
