Overall from what I could see in your video things look pretty good.
It was a bit difficult to slow down and see your arm action with the windbreaker on. looks like it was cold and wet outside.
I like your knee lift, stride length and hip action especially on the first pitch. Check your hip and shoulder separation, maybe hold back your shoulder turn a bit longer and check your elbow to shoulder height as you go from full external rotation to inernal rotation. Again hard to be sure with the windbreaker on.
At release do you feel like your body is fully behind the baseball or do you feel like your upper body is leading the way?
