The only thing I can find to "complain" about in this animation is that Aiva's head is twisted a little bit too far on her neck for the pose. You don't want her chin to be angled past her shoulder, and this is right on the cusp of putting a little bit too much twist into her neck such that the posing of her head becomes unnatural. So if her head had a bit less of a turn/twist to it than we're seeing here I'm thinking the overall effect would look better.
