Interesting choice of model, I'll be looking forward to see the outcome.
You're probably going to have a lot of trouble with this, as the model you choose for that texture doesn't resemble the concept at all. Not one bit.
But it'd be cool if you manage to pull it off fairly well. It's a creative initiative :)
Anyway it needs more contrast and as you're still working on it I assume you're going to add better highlightning & shading to it.
