I agree with Steven about needing more momentum. Front leg/foot swings out pretty fast and draws your attention but if you focus on his belly button you'll see it doesn't move much - especially early in the delivery. I'd suggest focusing on pushing his front hip towards the target sooner and faster. Use his back foot drag line (line in dirt created by his back foot after it turns over and drags away from the rubber). Shoot for creating enough momentum to result in a drag line that is 2 of his shoe lengths long.
I also agree with Pitcher17 about needing better glove side control. Looks like his glove flies open and then drops - these two motions can pull the front shoulder open early and can affect posture. Try to maintain an "equal & opposite" position until front foot contact.
