it's counterclockwise for this reason: the shadow of the wide opened feet is always pointing into the screen/away from us. Assume you see clockwise, the time when she's facing at you is the time when her toes are pointing away from us, that's impossible, unless that's not her shadow. In conclusion, if you are the people that see counterclockwise, try to cover her shadow and start imagining her being spinning clockwise (deceive your brain) then you'll see what right brained people see.
