I sometimes like to keep copies of all the steps that go into a finished illustration. This one is a little more straight forward than some - without much change from rough to final draft
The final digitized and digitally colored (you will probably note that I changed the head position and jawline from the earlier drafts).
Final inks scanned and digitally enhanced to prepare for color
Final detail Ink applied (using Brush-Pen).
Clean Pencils and outline in First ink
Rough Sketch
There are all kinds of intermediate steps - but the changes aren't very dramatic so I decided to trim it down to the images above.
