Lot's of good points. I am not going to rate you as it isn't fair but I give you props for posting a video for criticism and advice!
I would like to add, a problem with a lot of TMA schools is the disconnect between learning the technique and applying the technique. It seems the way in which it is learned (opponent 'offering' an attack) is the way it is continually trained even past black belt at a lot of places.
Training has to advance from an partner 'offering' a technique to 'applying' a technique. Like the bear hug in your demo, he's at the 'offering' stance, wraps his arms around you and waits. You need to have him gradually become more of an attacker; hold you tighter, move, all the way up to the end goal of a real situation, he has to grab you, squeeze, pick you up and dump you face first to the ground and you have to stop him!
After that he has to be a smart attacker, buries his head into your shoulder area to stop a rear head butt, place his foot in between your legs to protect his groin and give you one foot to attack(you shift your weight to stomp and he knows where you are attacking! you drop your weight, he drops his weight!
When you can pull off your technique with him attacking at is stage, you know you can defend yourself on the street with it. Actually, the technique you start with won't be the defense you finish with, as he adjust you have to adjust to a new technique to counter. It becomes organic.
I'm actually busy writing an article on the dilution of traditional martial arts.
Keep training! I'm 20 years in and still learning and refining what I thought I knew.
