Y.T. - Snow Crash - First Iteration

I recently read Snow Crash from Neal Stephenson and I wanted to do some concepts for the world and characters. This is Y.T. - I know she's originally 15 in the book but I wanted to keep the upcoming concepts and world sketches very loose, not caring too much about the descriptions that are in the book but more about the pictures I had in mind. The sketch is just the first step for the colored illustration.
