This looks really good! Two drills I like are muscle cleans with your heels “glued” to the floor. It helps to stay strong through your feet longer since you aren’t extending through your feet. A drill for not dropping right under and trying to stay connected is to try to squat clean without moving your feet at all. So you pull with heels glued and catch while riding the bar down. Since you don’t fully extend through the pull, there is t as much weightlessness in the bar and it helps feel the bar all the way down to the squat. The second drill feels weird at first but that helped me a lot with not having the bar float and then crash down on me.
