Pivot and weight shift?

[mb6606]

I understand the head should be postioned stationary throughout the swing at impact fix location. This feels like my head is positioned further to the left than previous with more weight on the left foot.

I feel like the weight only shifts slightly to the right foot on the backswing. The left leg and left arm becoming a post (hinge pin). The left knee bends slightly forward versus in and to the right. Feels almost like swing without a weight shift to the right?
Is this correct or acceptable???
