Playing away from your body a hell of a lot in the beginning. In the first lot of footage, rarely are your bat and pad together, meaning you are overbalancing a fair bit and leaving a large gap between bat and pad. Your foot only ever plants pretty much down the track on middle. Even on a couple of straight balls, your front foot went outside leg and there was a gap as you played it to the leg side. Work to play these much straighter as an extension to the forward defensive.
Much better from 5 minutes on when you started playing forward defensives and with bat and pad together.
Another thing you might try is to get a real good stride onto that front foot. It seemed a lot of the time you were in no man's land - stuck on the crease, not forward or back.
To be quite honest, I don't like your movement just before the ball is bowled of the back foot moving across, but that might just be what you are comfortable with. It means it's difficult to get back on the back foot to play a shorter ball (cut or pull) as there are too many movements, it squares you up a lot and leg stump bowling and short bowling just looks plain awkward.
