That's a lovely wave for cruising (I'm jealous!)
What I think you need to do is to stand up straighter and get your hips forward so you stack on the front foot more.
If you bring your elbows up and forward, that should help too.
Look at the Bosu Ball Neutral Stance drills for more advice.

Eng The Bosu ball lets you practice the stance on its own, without the distractions of having to think about the wave or the surfskate.
When you compress, you need to go forward like you're doing a lunge, to keep your weight on your front foot, instead of sitting back like you're going to sit on a chair.
Remember: compress to go down, extend to go up.
Keep the elbows high, preferably at chest level to remind you that your back needs to be straight.
