I used mostly watercolors to create the shadows around the eyes and blocked in the hair. Then added details with a black Conte pencil. And because the eyes nedded some highlights, I added them at the end.
This one had only blocks of watercolor applied to the paper in place of the eyes only. Then the rest of the features "appeared". I love smudging pencils, I believe the one I used here is a graphite pencil and conte black pencil. The hair was done last.
