how do you become good at making miis

i don't know to compare mii facial features ex: mii eyes to regular eyes. can someone help me be a mii expert

@kenleo101: Love Mii, I even filled up my roster thing

( if you're talking bout the Wii U version i have no idea, only Wii )

Well when I make a mii i usually keep the things in the default position. As for eyes, I often like to put glasses on, but if you're trying to make a certain person or character then i recommend the default or the ones most like the character/person your trying to make

I don't know about Mii's... but how about making Keys eh ?
