Can someone help me with my mistys? Tell me what i need to do and what i do wrong

I want to grind my first rail and I want so good drills to practice

Any tips on my mistys? I keep landing forward dragging my hands. its also the biggest jump on my tiny hill so if air time is an issue I cant really fix that

I tore my acl and i was wondering if there was anything wrong with my landing, if i couldve saved it? Please help me so i dont make a mistake next time i end up in a situation like this.

I ware sick for a week an when I got back skiing I always land my 360 too far back
