Tinker Bell Process

The sketch in the top left is what I started with.  As you can see, the lines are really rough and I really didn't know what it would become.  Once I added the wings, I thought that she looked like an edgy, post apolcalyptic Tinker Bell.  The other two sketches show the progression.  In the next version, I want to turn this into vector art and add color.  I know that most artists prefer Photoshop.  However, I use Illustrator every day and like working with vector art.
