Some tips on anime-style Miis without facepaint
I think visually the instructions are easy to follow: You use one of the dot eyes, then use the top eyelid as the eyelash, the bottom eyelid as a double eyelid, the top eyelash as an extension to the top lash, and the bottom lashes as a lower eyelid. You use the eyeshadow as the "white" of the eye. You can optionally use a mole as a nose.
I tried it on a character I was struggling to make, and holy shit! Holy shit!!!
Your mileage may vary, for example I've closed the game so I can't see how it looks on darker skinned Miis, but it works really well IMO. Hope it helps!
