After swing on the right, this one was a full motion, full speed one, not a drill swing. So much better at A6, still would like to see that clubhead more in. Just keep doing your drill and shallowing the shaft by working your left elbow "under". When you start to swing hard with your upper body, that is when the clubhead starts to kick out at A6.
Look at all the weight stuck on your left foot in the before. Much better with the after swing, buckle facing the sky, this keeps the arms straighter, more center contact because the club isn't "flashing" across the ball to the right.
Make sure the feet are turned out.
Helps you with turning more and keeps your head from dipping down. Not something you even had to think about to change to make sure those feet are always turned out.
So this is a big priority for you. Before swing on the left, club and left elbow getting too far behind you at A2. Want to feel that left arm fold into your side, in front of your shirt seam. Club head will be more inline with the hands.
Then from A2, you turn to 90 degrees keeping the elbows the same distance apart. So even though you've made a "bigger" turn on the right, the elbows are still in a good spot.
Not something you have to think about but want to point it out. The reason the backswing for you is important. Left elbow is too far behind you on the left pic, very tough to control the face and path. On the right, because A2-4 is better, the left elbow is in a great spot, leads to higher shots, better contact, straighter shots.
