Ok, feeling was good, but biggest potential for improvement is instructios. Instructions should be very much shorter and clearer. I need to get the show going on faster and with smaller steps.
Just give a simple goal and see what happens. I should not show the technique. For them to copy me technique, is not the goal. Goal is to learn a concept and understand it in own movements.
Now I worked like a traditional instructor. I showed a drill and others mimiced it. Ok, I tried to give to concepts, but it ended up being too long discussions.
