It's not really noticable, but Meiling has some awesome yin-yang eyes. is there a tag for those kinda eyes like Meiling has in this comic? I know there's a tag for unique pupils, but what about something like this?

Wow, you're right. I thought it was just typical eye shading, but all through the comic it's unique to Meiling. Now I'm wondering about Patchouli, because she's the only one in the comic without pupils.
