If I could do half as well as that, I'd be very happy!
It's a bit difficult to see, but I'd suggest you need to go more top to bottom. It looks like you're rushing out onto the shoulder and then your board is rather flat which is stopping you from getting on rail, hence the loss of speed and lack of spray.
Try holding the bottom turn for longer to get right to the lip, then leaning more into the turn to get back to the foam.
Still looks good, though 👍

You're in a side-on stance which is making your back arm swing behind you and stops you looking at the foam.
Check out the Stick Surfing/ Skating drills which will help you concentrate on getting front-on with your hands over the rails.
