Digital Illustration

Here is my new digital drawing. It is an illustrative sketch of a man in profile format. It shows the light and shadow effect generated from his face and the tonal variations.

There is also a depth on his cloth and a fading tone at the back of his head. How about the squiggles around his face? A thought for another time.

The piece was done with AutoDesk sketchbook application using scribble style. My steps can be seen below:

Thank you.
