Not bad. Your back ground shows with decent bow hand and bow arm, good posture and shot sequence.
What I'd suggest is on the string arm side of the shot. See how your string hand drops sharply at release? Now extend your view to the string elbow, it does the same thing.
That's, I think, a carry over from shooting a release. IF you can work on moving the string elbow around to the back (towards the fence) and more horizontally that will carry your string hand back along your cheek to a follow through position right behind the ear.
Right now you are kind of popping the hand down off the string rather than pulling back straight off the end of the arrow. That downward movement of the arm and hand is probably giving you some vertical spread on the arrows. So, my SUGGESTION is to move the elbow more horizontally and the hand should move straight back to behind the ear.
Good start! If you can on next videos, try to not have so much "back light". Can you move the sun??? LOL.
