This video should be called "John fights dudes in capes"

You won most of these fights, so you are obviously doing great! Your defense is excellent. I fought heavy before I took up fencing, so please forgive my presumption if I offer some observations about heavy. I have learned a lot from your fencing videos, and if I can so something small to return the favor, I'd like to. Fight number 3 against the leftie: Your sheild set up did not change against them. You might want to consider changing your stance against a left handed opponent. I set up with my shield a bit more forward and open against a leftie with the edge pointing more towards them. This gives them a much bigger obstacle to have to come around. Also, once you had him legged, you switched to goofy foot. Having sword leg forward makes it an easier target for a leftie. If you were doing that on purpose to bait them in so you could take their arm, that makes sense, but otherwise, I would not switch feet against a legged leftie. Another observation: when you retreat, I frequently see your legs wide apart, almost in a fencing lunge stance. That robs you of the ability to throw anything but a thrust. Other fighters will see that and press you. I'd keep my feet closer together and throw a shot as you retreat to clutter up their line of pursuit. You may have thought of all these things, but I hope you don't mind my sharing my observations.
