I've had the concept of a kick-butt ghost hunter lady floating around in my head--What if we had essentially a ghostbuster, but she's a tired business woman who is unfriendly and rude and witty, she hates her job as an exorcist and a paranormal investigator because demons scare the daylights out of her, but she does all this anyway for someone she loves? After sketching her endlessly and playing with facial shapes, expressions, and writing a deeper and deeper story arch for her, I think she's ready now to be modeled and played with in 3D.
I think a lot of Kristen's character will come from the way she expresses herself, her dry humor, her intolerance for shenanigans, or like, a moment where she's screaming and acting like she's totally not scared at all to save face. I'm looking forward to see how I can further experiment her once she's animated and moving to really sell that expressiveness.
