If you try to keep your triangle longer (one piece take away) you might by default get a little steeper in the backswing. Maybe try to think of this paired with getting the left shoulder under your chin at the top. You might get steeper back and just drop right in the slot from there. It looks like you get a little handsy on the way back and snatch it back like. Try to have a buddy take a slow motion video so you can compare that to a pro. I'll attach mine just for fun (I by far am no pro) and you will see I have my own set of flaws. But the slow motion really helps me see the swing well. Then you can compare your swing to any of the thousands of down the line "pro" slow motion swings that are out there. I think this is pretty valuable actually. The fist thing I noticed in my video was the hit instinct is clearly visible from the practice swing to the real swing. Anyway. Good luck with it.
