As before I think you should pay attention to your initial posture and work on eliminating the head drop at the beginning of leg lift. This big drop is directing energy into the ground which must then be counteracted before you can move to the target. This slows you down and limits the amount of momentum you can generate toward the target.
One way to correct this is as I said before. Set up in a more athletic position with a slight bend in the knees and a slight lean at the waist. You seem to have a little bend in the knees but your torso is very upright. Adding a slight bend at the waist will serve to put you in a position more similar to the one you move to as you lift your leg without having to waste time, energy and changing posture to do so. You’re initial forward lean is very evident from the rear view.
As for your rear foot coming off the ground most elite pitchers have some sort of drag line although a few don’t. Those that don’t are in the minority. IMO drag line is a good thing and can be used as an indicator of previous events in the delivery. Fix your posture first and see if that has an effect on your drag line. One step at a time.
Other than the posture issue I like you’re athleticism and the way you control your glove and finish. Once you get started you’re head stays on line pretty well.
