First off great improvements, and I like the swing sequences. Looks like you are really on the right path and almost there.
Looking at the swing sequences you posted, looks like at A3 and A4 comparing you to Rock and Waite, your right hip hasn't moved back and up as much?
Don't know if that is a key to help you create more space on the down swing and have your right leg move more towards the target and less towards the ball?
As Mike mentioned, not many have a right hip like Grant. But I'll also add that my shirt is untucked in the sequence photo. I typically tuck it in, but was wearing a new pair of Hurley shorts that I picked up a few weeks back and when I bought them, I didn't realize they don't have a belt loop. They are basically board/surf shorts - that look like a nice pair of shorts. I love them, but tucking a shirt in - with no belt looks silly. So I need to redo the swing sequence with a pair of pants/shorts with a belt and my shirt tucked in. Then I think you can get a better baseline for where my body is in correlation to the swing model used (Grant in shorts).
