Overall I like his demeanor. I like that he stayed calm but I agree with tiny in that he doesn't seem to have the best timing. I would have started the horse much differently with different exercises as he seemed to be missing some pretty basic stuff (the horse) but the result in the end would likely have been much the same considering he only had 4 days. He seemed to put himself in some risky situations if the horse had decided to fight rather than flight.
I am not sure if I would have wanted to take on a horse that green for only four days...seems to be setting horse and owner up for failure. I think it shows well how multiple training methods can work if you have goals in mind of what you are looking for and remain patient and give a release to the slightest try, which he seemed to do well.
