I only watched about three minutes. You were hitting pretty well, so you obviously have a good understanding of sight alignment and trigger control. Your gun handling needs some attention. It is important to get quality instruction and coaching to so one does not spend time ingraining habits that must be over ridden later. How we reload, manipulate the slide, keep the weapon in our work space, access our magazines, etc. should all have a fight focus as to why we do them the way we do, with the objective of developing habits our subconscious can access under the speed and pressure of the fight.
Notice how, at 2:47, when you changed mags you used an under the slide technique to drop the slide and missed and had to make a second movement for it to work. That technique may be suitable for doing a chamber check, but not for aggressively manipulating the slide when getting your gun running again is the priority of the moment in order to win the fight.
My feedback is based on the assumption that you have a desire to develop fight proven skills and not just be a "plinker." If having fun shooting is the only goal and activity you plan on doing with your guns, then you can do it any way you wish because the only thing that matters is being safe. But should you wish to have the skills to fight with your firearms, then there is a right and many wrong ways to do things.
Onward and Upward!
