@gino maybe you would like to hear some criticism: sound isnt balanced among multiple videos, the out of 10 grades seem somewhat made up and provide no usefull information, (how is 7 average?) better to give two more descriptive sentences on each department of play instead of it. Also, i think the intro is long for given the format, i would crap it completely.
Nonetheless, i aplaud you for taking your time and having courage to help grow our racket loving community. Cheers to you mate!
