Olympiads - Medusa Redesign Picture

After completing the cg character models for my 4th year film characters a few months ago, I've been getting them looked at and come to the conclusion that Medusa's design felt like it didn't fit with the others. To remedy this, I will be restructuring her model, and to do this I've started out by working on a concept drawing. I'm trying to take a more unique interpretation to the design of this character, I'm hoping it comes through in the model.
