The character creation in AoC is already the best among all games.
Now let's have in-game tattoo artists?
Intrepid's job in this will be letting players upload a few decals following the game standards.
No profession or in-game system is required, no nothing, this is just a player driven profession... the player will call himself a tattoo artist and will trade decals.
You could:
- it's an item and it will have your name on the Info about the item, who uploads could write relevant information about the tattoo in the description like if it's a one piece tattoo or if it's a part of a set
- option of marking the decal as unique, so it will only have 1 unit of that decal in the entire server
- sell your decals as much as you want for any price you want, people might even resell the decals
Players will tattoo their in-game feats on their bodies... their motivional words, their node name, etc, whatever, I wanna freak out when I see what other people created
GENERIC TATTOOS:
So you could sell and buy generic tattoos from in-game tattoo artists, people might buy all your tattoos and judge that one one decal is not great then they can upload just a new decal with a better design
So if the player bought a set of 5 decals, he could actually throw away 1 and upload a better version of it...then the tattoo will look better. He could even upload a few more and close his sleeve with more stuff
UNIQUE TATTOOS:
Or you could have decals marked as unique unique so only one person can use it, so real life artists and tattoo artists could actually upload high quality art into the game and only you will have those tattoos.
EULA:
Add relevant information in the EULA, the person should give the rights of the decal to Intrepid, bla bla legal stuff
OVERLAPPING TATTOS:
The character editor needs to let people overlap tattoos so we can put together decals with different colors so we can have colored tattoos:

This tattoo could be drawn in Photoshop or Gimp with 8 layers, each layer is one color, so I would export each of my layers as eight different decals.
Then in AoC I would upload those 8 decals and in the Character Editor I will decide which color I apply to each decal and I will be able to make a tattoo with the same quality as the picture above.
The meta game in the tattoo world in AoC will be having an unique colored tattoos, so only that player can use those decals, he could sell the decals tough... the decals will remain unique and the next guy could apply other stuff around it.
SO PEOPLE WILL BE ABLE TO CLOSE THEIR SLEEVE

Let people tell their stories through their tattoos
Who's with me?
