With respect Sensei, your power and tension look way off. It would be easier to see if you took off your gi top. Also you unnecessarily bounce twice at the start, your feet aren't turned in enough. As a black belt, if you show students this kata they will also practice the same way. You will eventually dilute the kata.
I was in Germany and they made the announcement that no gi tops could be removed - I was not going to do Sanchin kata until they said that, which threw me from any chance of winning, but it showed that you cannot limit the indomitable spirit of the true martial artist: Sanchin kata is to be done shirtless or it’s conceivable that you’re hiding something or never do it if you have beliefs that contradict it 👌🏽
