Looks like you made efficient use of the ear polygons, Clarkie!
It would be great if the ears were a seperate morph to everything else, then they could be applied to any Roxie head without changing other facial features.

Well, except for the little bump on Roxie's Bum where the tail fits, that is all I've done for now.  Although I am thinking of  giving her face a more feline look. around the nose and mouth. Of course, the only thing I can see them being used for is catgirl ears.
