Your legs are too static, you need to work them more by extending into the top of the bump and letting your knees bend up into you. Your legs sort of maintain the same semi bend throughout so you’re not getting the shock absorption. Also, your upper body is turning to much, there’s not enough
Upper and lower body separation. You want your upper body in the fall line pretty much the whole time, you’re instead rotating your upper body perpendicular to the fall line. You’re leaning back too much and sometimes lifting the uphill foot to initiate or stemming. If you get the upper body into the fall line and improve the timing of the pole plants it’ll go better for you.
I know that was critical but honestly it’s sick to see young people skiing bumps.
