This is an extreme position. You would have a hard time finding many/any players in the model hitting thread that ever reach this position with the back elbow so that would be something I would study and see how that affects other parts of the swing downstream.
Think I will comment on my own post now that I look at the image I posted. Why don't you rotate that top hand a little? You don't need to line up knuckles but get somewhere closer. Those hands are way too opposed for the arms to work together. That's one of the reasons that elbow is up all crazy.
