Hi Carolyn, you were so close the first 3 times! It looks like the one thing missing from those and the reason you got it the 4th time was because the tail across your lower back was higher above your booty (mainly on your left side)! As you pass your right leg between the tails focus on getting the tail that lays across your lower back a bit higher on the back. I think about sinking my hips down towards the right side strand just slightly until I feel that tail rise higher along my lower back before raising my left left leg / separating the tails for the invert. Hope that helps!
