Luna is a very proud princess, not fancy at all, not girly either, and still a strong pony and Princess. She defends everypony's dream every night, she fights sometimes, that's why I chose a matte knight look for the armor with a bit of fanciness because she still a princess. The dark color of the white parts of the eyes made her more mysterious and serious-looking ~
