Final:

The lines are done traditionally, ink on bristol paper. I spent so much time getting her legs right that her hand was very wrong initially. I ended up using tracing paper to fix her hand, then I scanned and composited it in Photoshop, then did the colors in Photoshop, because I've misplaced my watercolor pencils.
I'm happy with it for now. I really enjoy doing this style of art.
