I started by drawing in my sketchbooks, for some reason this woman with bloody hands and mouth came to mind. Don't ask me to explain why, I'm just glad that ANY images come out some days. I had originally planned to do it digitally, but the fastly-approaching deadline and lack of confidence with a digital tablet made me decide to do it in pencils, which I have not done in years, so it'd be interesitng to see if I still could.
First the basic outline in pencil, then shading in the flesh and hair. I use pencils the way I imagine I would use paint if I was any good with it, in layers, with H pencils first then getting darker with B pencils.
Then the clothes and starting in on the blood. I used some reference to make sure the blood looked "right," but I soon got a feel for it without depending on other pics for too long.
Then the bloody hands and clothes, and overall darkening, though I don't think you can see the subtle changes in these shots.
And the final result. At least I'm considering it such for now, I'm not sure of a background or even if it needs one. I'll decide after it comes home from the show after Halloween. I'm not sure of her story yet either, other than she's done something awful but can't quite recall what, which I hope I got across with her expression. Earlier ideas were less subtle, with spectres all around her or a victim beneath her. I'd like people to think up some ideas of their own, perhaps.
