Claire is pretty good looking, but I love Sunny's natural smile. I have both of them in a family of mine, but I don't have the pictures handy.
A lot of the makeovers here are really good, but I tend to think that a minimum of makeup is better, and only to accentuate their facial features. I have maybe two or three sims who wear makeup in all my games. I just don't think it looks that good on most sims.
