This is more of a comment. I took a lesson from Michael Jacobs about a month ago. You have some of the same issues that he pointed out to me.
I was more across the line than you are, but similar. He showed me how steep I was in the downswing. Called it swinging down through my neck.
He wanted me deeper in the backswing and didn't want the shaft past parallel. We ended up bringing my Vertical Swing Plane down by about 10 degrees on the 6 iron. I felt sort of like Steve Stricker, but hit it better.
You have that overdone backswing and steep downswing path.
