Video as feedback - swing

I used my camcorder as practicing my 5 iron. Swing is intentionally slow so that I learn it. (Not the tempo - of course, but the "postures" or rough movements.

Here is an example of my current swing.

Balance is not stable at the end position. Shot opens a little - often more:-)
Basics are there, but need a lot of repetition.

My head might be pent a little too much down. In the end of my backswing - I lift my head - maybe my shoulder does not have room enough to turn - and I have to lift my chin up?
