I'll suggest more tattoos & facial piercings in here. I'm a fan of the alt/goth style and it'd be nice to have those options. (If you don't like them, don't use them, simple.)

Eye glows would be neat.

More long hair styles, less straight-across bangs please...

Black sclera options for more than just male auri.

Far, far, far more makeup options, and for the love of gods please let us have darker makeup like lipstick on miqo. 'dark red' or 'black' is just a light shade.

Nail polish that isn't tied to the false nails.

More intricate earrings, ESPECIALLY for elezen. I have elezen alts I'd love whole-ear jewelry for, but any race with large ears could benefit from this. Would it require a lot of work? Yeah. So? AAA gaming company. Put work into it.

Sharp teeth options (why did they nerf miqo fangs...?) for all.

Auras could be pretty neat.
