Here, have a lovely picture of a barbarian princess
Though, I'd wager she looks more Celtic than generic barbarian.
I like this more than some of the pictures you see of warrior women in fantasy art - hot babes in as little armor (or clothing, for that matter) as possible. I could see her riding down enemy infantry or wild game. Maybe she's patrolling the borders of her tribe's territory, on the lookout for poachers or spies.
