1. yes. 2. it's 'stuck' to your base like it would be if you got a tattoo IRL.
You can remove it though, but I wouldn't recommend that, since they can be pretty expensive, at 500sP per pixel.
As long as they're not fake eyes or clothes, anything is allowed! :3
I a little confused about the images we choose to be our tatoos.. Do they have to be actual tatoos?? orrr.
the SP isn't an issue
