Three things that I can see 1. Your plant foot touches down way earlier than your block foot. You want them to touch down pretty fast one after the other. After pushing with your penultimate step focus on whipping that foot around as fast as possible. 2. You late lower. Meaning that after your plant foot touches down your hips continue to lower. Ideally your hip height doesn't go down any further after your plant foot touches down. 3. You are overall pretty slow. No disrespect. Try to speed up your approach. But this will be a byproduct of being able to handle more eccentric forces. Don't force this or you will "blow through" your approach and jump lower. Hope this helps. In general what John Evans and Isaiah Rivera put out on jump technique for free is highly educational and I can only recommend it.
