Hi there! Really great work so far. We know this one is a toughy so we are so glad you are not giving up!
Here are some things to try-
1- When doing the first part of the drop when you straighten the wrapped knee, think about releasing the top hooked knee more- like a very light, loose hook.
2- When doing the rotation portion of the drop, try to bend your knees on purpose in a “stag” shape.
3- Maybe wear a slippery fabric top? That may help with the ending position before the beat.

Let us know how that goes. We commend you for all these awesome attempts!
