Yep and some will do "magical" alterations such as scars, wing designs, etc and some wont. Its all up to the elder in charge at the time.

I've paid up to 500 gold for a full body tattoo with a max length description. I've also had a tiny rose with again a max length description and only paid 100. Again its up to the elder at the time.

Some things I've had a problem with in the past:

Wing designs (anthian, secian, drake): Some elders will not do it and tell you to wait for a special peddle, however we haven't had a wing design peddle in ages.

Scars and things: Once I wanted a scar across my face with a milky blind eye. Wouldn't do it. I once asked for a thorny chain wrapped around my wrist and up my arm but since it was supposed to be a real chain and not a tattoo I got turned down.

So you can kinda see what they will go for and what they wont.
