Actually, judging from your pic, I think you'd probably look really cute with a nostril piercing.
I'd say a Marilyn/Madonna would be good too. An eyebrow piercing would get kind of lost if you have long side bangs.
Tongue or septum are good if you want to be able to hide them.
Another fun one (even though it isn't really on your face) is your tongue web. No one will know it's there unless you show them, but you will know it's there.
We're all fools, whether we dance or not, so we might as well dance...
Currently have:
6g and 16g L+R lobes, 14g L inner conch, 18g R nostril, 16g tongue web
On my wishlist:
L Industrial, L tragus, R spiral cartilage, R rook, R anti-tragus, septum, set of 4 tattoos
(I think big, lol!)
