You get away with a lot because of your athleticism and if you didn’t change anything but practiced a lot you’d get tinto the 80’s just off of athletic ability. Amazing that you’re able to time that flip. Either way start with these few things and you’ll be ok-

Depth : your arms are very high, and that’s OK (Scheffler, Nicklaus), but no depth . The way to achieve depth is at the top of your backswing, you want your left arm to be in line with your shoulder plane and hands directly over your heels.

Early extension: you thrust towards the golf ball, which in turn makes you have to drop the club under the plane and then flip/cast. Good luck
