The video was a little short and choppy, I’d advice taping a longer session from various angles. You’ve got pretty good base mechanics. Only things I really noticed were:
Your stride length seems a bit short for your height. (Striding farther will get you lower to the ground and increase your visual velocity).
You are rotating your shoulders along with your hips. If you can increase your hip-shoulder separation, you will apply more force on the baseball.
You have little forward trunk flexion. By flexing towards your target you will keep the ball lower in the strike zone and you will see an increase in your velocity as well.
All in all, you look pretty good. Keep working hard!
