To my crazy brain: clockwise, all the way and only way lol.
She appears to be spinning from right to left, and to my head that equates as clockwise. Also given the angle of her foot, and the momentum, I would be inclined to believe that the model “spun out” with the left leg, rather then spun in with it; i.e. she started to spin with the leg moving away from the right leg, rather then towards it; thus starting the loop anti-clockwise, but appearing to be turning clockwise at first glance, in so far as my brain works.
Because who would have noticed her leg in the first frame lol?
Descriptions there and else where relating to the right cerebral hemisphere seem to connect well enough with how I think :-/
