Martial Arts on Youtube?

I just put up a video on youtube, my first. I am wanting some feedback, to see if there is interest. Want honest feedback only please. If it is liked I am thinking about doing more. Once on youtube type "cagedraptor" as search. It is a tire training video. Thanks for helping out. The question(s) 1. is it something that is useful

2. do you feel I have the ability to teach others. Just do not want to put up video if the larger part of those that look at it will consider it useless or unskilled. I have my own views but I want to do this to teach and help others. If that isn't going to be what others think then I do not see a need to put the time and effort into doing them.
