Ah yes... Vicky just doesn't know what to do with her cheeks when she rotates her thighs so much. This is normal, I'm afraid.

You did not show the amount of abdomen bend with respect to the hip. The only thing I can suggest (without getting into custom morphs) is to reduce the arch in her back a bit, which would permit a lower thigh rotation for more or less the same overall position, and perhaps reduce the size of her bum for this pose, using the Morphs++.

The only really relevant values are the Bend of Thighs and Abdomen.
