How to Tee-Off without getting Teed-Off
By the time you've finished your swing your head should be almost a complete head width towards the target.
However, your head should still be behind your lower body, i.e. your hips. Your lower body should always be in front of the upper body from the transition on.
Now because your swing should have such a strong lower body drive towards the target it means that at the end of your swing the sole of your right foot should be almost completely visible when looking at a golfer's swing from down the line.



At the
finish of your swing your knees should be very close together, if not
touching.
And your left leg should be almost dead straight.
This is a good reference to know that you've used your lower body aggressively in the downswing. If your knees are a long way apart at the end of your swing that's a sure sign that you haven't used your lower body aggressively enough in the swing.
Now I want to mention your weight distribution -- because at the finish of your swing 98% of your weight should be on your left side. And more specifically the weight should be mainly in the heel of your left foot and your left hip.

At the finish of your swing 98% of your weight should be on your left foot. And more specifically, most of this weight should be on your left heel.
So that's an overview of what should be happening in your follow-through and at the finish of the swing. This of course should be happening naturally. If it's not it will be as a result of bad habits previously in the swing
Fix those and then your follow-through and finish will automatically improve.
