Hello:

At set-up you may want to have your hands slighly further from your body. Not much but maybe an inch or two. Try to get into a better posture with your rear end sticking out and your back a little straighter. You don't need to be rigid but you seem a little slouched. These slight adjustments can be seen in the down the line view.

On the head on footage, again with the set-up you may want to be a little more tilted away from the target, not stacked on top of the ball. Remember the right hand is sitting below the left so you should have that same tilt to your spine which will automatically tilt the shoulders correctly. The feel here is that your left hip is slighty higher than the right. This will feel a little uncomfortable at first but this is essential to being able to turn and maintail your posture throughout the swing. Finally watch your left knee drifting in too far toward your right knee on the backswing. You want to maintain some space there which will build torque into the lower body action. You can practice this by using an inflated ball (about the size of a bowling ball) between your knees and keep it there during practice swings.

Overall your arm positions are good, not tense and the right elbow is in a good position to deliver the club back inside on the downswing. Also you seem to begin the downswing with a nice syncronized shift of the lower half leading.

Good work.
