At first, there has been quite some brainstorming about the head. Several types and hairstyles from what I was thinking for this character and here is the result. Katie outdid herself, offering me a lot more than I expected, letting me select the perfect head.
After that, there was quite some work on the main outfit. I sincerely apologize to Katie, I was quite stubborn on this part, thinking already about the story and not letting her free to invent something creative.
