Looks more like a hitter's 'carry back' rather than a true swing. Either way you look to be closing the clubface on the backswing.
Work on finish swivel and you'll find that you can 'allow' rotation on the backswing, it will also help you get your pivot to move through to a full finish better.
Eyes closed, heavy club, back and through, back and through. ROLL on that line!
