DEPTH ALERT! NEED MORE "UP" with the right elbow moving off your chest and, to use a phrase PGA Tour players will use a lot, "staying in front of your chest."
Note that the two lines on the right arm aren't 3D but they highlight how much less his elbow has rotated around his body and how it's strayed a bit from his rib cage. Or to put it another way…
Relative to the camera, your upper arm is pointing to the camera's left, while Tiger's upper arm is pointing more at the camera. The only real trick in this is that you have to do this but still keep up your rotation - you can't just pick your arm up and point it at the camera with less rotation.
Try this: swing back doing nothing at all with your arms. Just pivot to 90°. The hands will gain PLENTY of depth. From there, bend your right elbow (and let it move off your rib cage a little), cock/hinge your wrists, and blammo, A4.
This depth is extreme and is going to cause problems when you're able to hit golf balls again.
Yea, really can see the difference there. More to work on. TO THE CAMERA!!!
I think the shoulder and hip angles look pretty good in that image. So, just need to work on how the hands work in the back swing. More up, less deep, trust the turn gets the required depth.
I do what I can
Yea I was able to swing with the original configuration, but not optimal for camera usage. So the couch got relocated and so did the chair. Now when I want the room to be normal, i just shift the chair more towards the right. It actually works well aesthetically, really opens up the apartment more.
