Hi Roger, what stands out to me is that there's a lot of movement going on in your upper body but the board is not really reacting that much. Maybe try slowing it all down and leaning a bit more too instead of twisting so much. It also seems to me that your legs are quite locked. A bit of skating would probably really help. Have you ever tried it?

You've done the hardest part. You've put yourself out there and asked for feedback.

What stands out to me is tension in your body. Your staying compressed for a very long time. When you're just rolling there's no need to. Stand up and chill a little. Only compress when you're about to jump up. For instance when you're bmaboit to go up a transition.

Your feet, your back foot especially, are probably going to move around a fair bit. I'd recommend not worrying about it too much. Try to be front on and your feet will follow.

Im looking at your right hand. Open it up will open up your shoulder too. Think of it as serving a pizza on a plate to someone behind you.

Like graham said: At the moment you are using a side to side movemen to generate speed. You're hardly using the walls. Try going up and down the walls to generate speed instead.
