Line drawing.  Darkening some of the shadows.  This drawing is on bristol board.

I went a head and did the midtones in the background.  Doing this helps me get a nicer contrast with the shading.

I went right in to the hair.  Normally, I wait until the end to do the hair, but this time I just dove right in.  I also darkened the eyes a little.

Some more of the hair and midtones on her face.

Working on the hands and completing the hair on the other side.  It's time to start on her face.

Adding some shadows and midtones starts bringing her to life.  She is starting to look like Leia.

Working on darkening the midtones before darkening the shadows.

Starting to go dark on the shadows. I like my darks almost black.  I love contrast.

Here's te final.  I threw in a stylized background.  I like the viewer to see it's a drawing and this rough style depicts that.
