I have some experimental ear morphs that didn't make the final cut. They lower the ears, and fold the ears back along the skull. Why weren't they included? Because they don't play well with the other ear morphs, and severely muck up their posability.

Still, if you want them, I can pack them up for you. Caveat emptor.

A better solution might be to adjust the ears' joint parameters, permitting them to fold the way you wish. They aren't easy to tweak, though.

As an aside, you might want to change her brow-colour to red, to match her hair.
