Here's the black and white version wanted to keep it simple and strong and decided to try out a bit of a textured crosshatched background.
For the color version to keep with the background style I tried to keep the same crosshatch style to give it a comic book, pop art feel.
It was a good way to to save on time with out getting into heavy rendering. I'll probably still going in to it at a later time to give some more detail, rendering and attention to her mechanical parts.
I usually post my #sketch_dailies on my twitter when I get around to them, or even on my fb page.
