I had a hell of a time trying to come up with a female TF, and head design alone proved to be pretty challenging. Since female TFs are a rarity, I reckoned I'd post her up.
I came up with a head first and have been doodling from there.
Response will dictate whether or not I get around to doing a nice "On White Paper" cleanlined version of her. Suggestions for posing would be great too.
About her personality, she's very brash and reckless and more likely to punch you out than shoot you.
Haven't thought it through much further than that.
