Finding the Character

We've all had those moments: You have an idea, a great idea but it's not yet visceral. Maybe it's an emotion or a vague image, but the more you try to find it the more you come up with new ideas and none of them end up on the page because you're not sure which to start with! While that a great start, it's not very helpful for solidifying a concept. When I run into issues like that I just sketch. Messy or no, I get it onto the page and see what I can. I explore the character through the drawing and compare it to that hint of an idea I started with.
Ironically I learned this through storyboarding- you won't know if a camera angle will or won't work until you sketch it out and see it. The same applies for me for character design.
In this case, I have a character who is insane. I know that I want her to have a poor relationship with technology, but I'm not certain if I want her to have embraced her enslavement by it, or completely left it behind and turned to organic shapes only to define herself.  In otherwords, I'm still exploring her origins. Ultimately, i'll choose whichever origin helps the story progress the most, but I find that sketching them out helps me explore what the story would be like with each origin.  Neither are really working for me, but at least I know that those two avenues AREN'T what I was looking for, so I can continue to explore knowing what did and didn't work about each piece.
