Hungry for Fashion

Here's a update, in the form of a character design, for my short. This is the fashion model character who would be on the verge of death. I'm thinking she just looks like a topical fashion model and not like she's about to meet her end? Back to the drawing board! Any ideas?

I also experimented with having my characters on a white background verses a gray background. I think I like the white one more, but it would seem that most animation character designs are done on gray backgrounds. Any opinions on the matter?

Some first attempts at creating silhouettes.
