I think longer rope reins (single rein) will be best. That way, you can completely drop one rein when you pick up the other , say, for a disengagement or what ever, and the reins will stay on the neck. no chance of losing one of them.
I agree that you have too much kind of "gray" contact with him. meaning, you have contact but it's not super clear why. Using one rein at a time with him might work better to help him clue into the meaning of a rein, but having two acting on him will give him something to brace against. You could also try a little bit of just asking him to move forward without much guidance of his direction, to see how he handles just moving out , forward.
I thought your rode beautifully and were very patient and calm.
ETA with regard to the head carriage. It didnt' look high to me, but then I am not a WP rider. he did raise his head during your request for back up and a couple of other times, and you don't want to "pull' him down by lowering your hands. YOu can follow him up with your hands and if you want him to lower his head, keep a soft contact until you feel him drop his nose , then release. But, other than him raising it out of frustration and confusion, you probably don't need to worry aobut his head location for some time.
