I only have 12 right now.
Though this week I'll probably be adding another six holes, and then four more the week after that. I'll update once I have all ten. (Two orbitals, two vertical industrials, one horizontal industrial. All on one ear, arranged in a kick a** way. xD)

Thats my right ear. The left is pretty dull right now, I only have it pierced once and then a second hole stretched to 2g. (I've upgraded gauges since this picture.) Oh, and I've got a second conch piercing in there now too.

My four facial piercings. (Plus my kitty: Mister. Isn't she precious? xD)
I'll probably stop around 30. Give or take.
I've got most of them planned out... its just a matter of time.
