. . . Step 5 - with pressure on ball of the right foot, right foot pointing diagonal center, hip flexor raised to partner and center turned towards partner; isn't obvious where the head would be.
There is this common notion that the nose follows the toes, so
you've pretty much answered your own question.
It is quite interesting, though, how many varied opinions there
are about how just the "small" handful of movements in VW
should be done. There are coaches who believe the right foot
should be a flat side-step draw, those that like toe-heel, etc.,
irrespective of what the ISTD books may say. There are those
that believe in an oval travel around the floor, there are those
that think a diagonal is better, etc.. There are those that like
being very still in the upper body, there are those that think
minor "twitches/pulses" enhance the movement, etc..
Bottom line, as VIT observes, is that everyone (and every
partnership) does it a little differently.
