What did you draw from to create your character(s)? What experiences, thoughts, etc.?
As I said in an earlier post, the main idea for the main character came from a rather odd dream of a snowy ruined city. Aside from the setting, the only thing I could remember from it was a girl wearing a red scarf making a living within the ruins. I couldn't even remember her name, thus I just started calling her Scarf Girl. The way she acts and her obsession with color in that rather colorless world is based more of my own interests in color and how it can bring life to an environment.
Her companion, whom I just call Hat Boy (I'm really original and thoughtful about these names, I know), was created as a need for someone for her to interact with when I decided to make an animation with her a few years ago. I never ended up using him for the animation, but still that was what he was made for and his character is still based around that intention. His main goal is just to interact with the only other person in his world and make her happy... even if he has a rather crude way to go about it.
