In fairness this doesn't necessarily have much to do with character creation.
I like the OP's suggestions that your tattoes or warpaints may have signifance like an allegiance to a clan, guild or other faction.
It would also be cool if you could create your own designs and chose where on your body you wear them.
On a similar note, there was an idea in a thread about law that suggested you could be branded when you commit a crime, marking you out as a murderer or theif etc.
All in all, I like the idea that you'd collect tattoes, markings, brands, scars as you progress. I like the idea you earn them through your actions.
