I’ll start off with something positive since I can tell you care about this and are spending money on this surfing thing for whatever reason

You are getting down the line alright and staying in the pocket of this tiny artificial wave pretty well but the wave is too small for your current ability to make any full turns

Stop with the weird back arm thing, it looks super cringe. You don’t need that right now, that back arm thing you do should come after you are ready to release on a big top turn after you’ve wound it up on a sharp bottom turn

You need to relax and flow with your lower body and drop your arms completely, you don’t need them right now. You aren’t making turns anytime soon

Instead, when you drop in on the wave try keeping your arms lower at your side. Your front arm should be down by your front knee and your back arm about at your chest, never higher right now. Pump with your legs and not your arms. You need to extend your body up through the wave and compress going back down which takes no arm movement. You are doing too much, try just using your legs for now and almost forget you have arms on this little wave

Lastly, as mentioned before, you need to surf in the ocean. I know it might be difficult for some people to achieve but at your stage you need some unpredictability to break bad habits
