Gotta tell ya, you have a damn good approach run. I like how tall you run, you're relaxed and the pole drop looks pretty good. That's one of the toughest aspects of vaulting. The only real "hard" part you have to fix is a free take-off. The problem is you like to "block" which makes feeling comfortable with a free take-off very difficult. You don't quite "jam" a straight left arm like alot of vaulters, but it's damn close. Both hands should be pressing straight up aggressively, but at the same time the shoulders must be relaxed. This allows the body and chest to move into the "pocket" upright and get the biggest pre-stretch possible at the jumping take-off. You should get the sensation of "pulling the pole in with you during your take-off jump". Blocking gives the sensation of "pushing the pole in with you during the jump". Here's a picture of one of my young athletes hitting a good take-off position where the COM moves into the pole as much as possible.
The only other issue I see is you loose control of yourself in the swing and inversion off the top of the pole. Do you work swinging "bubka" drills on a highbar? You should. It will help you stay in control of the swing and inversion. It's details at the end, but you also end your vault up top way to soon (mostly because you loose control in the swing). You literally let go as the pole is still recoiling. Work swinging "Bubkas" on a highbar to help learn control of the swing and inversion.
Keep at it, you have some great potential.
