I feel a little silly jumping in after Daryl's wonderful analysis...
It looks to me as though you are trying to set up with your right forearm on plane, which I really like. Just before you take it back you look like you straighten the right elbow which gets the right forearm off plane, and opens your shoulders.
I would ask you to keep the right arm a little softer, and the right elbow/forearm lower than the left at address. I believe that will square your shoulders and help you get back to that little draw.
This of course along with Daryl's advise!
Please keep us updated. You have a beautiful G.O.L.F. swing.

Kev, you are a Pro. Daryl and I are Moe's. And not of the Moe Norman variety. More like Curly, Moe and Shemp. Mike O is Shemp, Bucket is.............
