Hahaha, yes, I have this figure earmarked for a Rogue Trader as well. haven't painted it yet. Clever inspiration you chose, very nice!
That's a nice miniature and you've really done her a nice job there. I love the little details like the belt full of keys and the compass-like device in her left hand. It's good to know some navigation when you're the captain of a tramp steaming through the distant corners of space. Very well done!
