Here is one I did with your DD. You can see why we call it DBSF. The other think I would note is as others have said when she does step forward her whole body and hips and everything start releasing forward. Look at the sequence and you can see she is too far forward in each sequence. If you want your can ask questions about each pic but I think you can almost start to diagnose for yourself what is going on. A final thing the stills and the gifs go hand in hand you can't mechanically get into each picture in the sequence and your swing will be magic it has to flow.

Omg, this helps so much more! DH can look at her swing and tell what all she does wrong. I look at her swing and know that something isn't right, but I can't ever pin point what it is because I honestly don't know how it should look.
