Your witch has such a cute profile shape!
Also, while I'm not presently able to pull reference images—remind me to peek the ear presets for my Musa. I used that class to portray an IC half elf, and I know a few people do similar using that class. I started with someone else's preset in the beauty album and then played with it from there.
I know the title of the thread mentioned Witch in particular, but if you decide to make a male character, it's some food for thought maybe?
Musa can do elf ears pretty well too, yes.
Warrior and wizard as well out of the male classes that I've tried or seen it done on.
Ninja was a big nope when I tried. Strikers can do them pretty well too though.
