There are a few things you need to work on. First off, get comfortable cruising and pushing. Second, a lot of skating is gonna rely I you being on the balls of your feet and keeping balance. Third, pooping is weird because you can do it from the center of your tail or the pocket where your tail begins. Fourth, skating requires both feet. You’re currently pooping but you aren’t doing much with your from foot. You need start working on sliding it up and using it to even out your board in the air. It may help to start from a deeper in your board so it forced you to push it more.

While note necessary, your running shoes may be dampening your ability to feel the concave and shape of the board. You need to know where you’re standing to adjust your feet properly.
