CAn i talk angles rather than compass points. North is 0 degrees, West is 90 degrees to left.
From what i've seen, i would say that in normal closed hold position, the head should be about 30 degrees. In promenade position, it would be close to 90.
One thing that does make me think a little. In normal closed hold, the man turns his centre to the lady. without having a twist in the spine, this would rotate the shoulders very slightly to the right of 'straight ahead' (i.e. north or 0 degress).
Have i got this right? It means that the head would start off to the left of the man's body alignment.
