This was the first in a series of drawing done with a calligraphy pen, a paintbrush, and a little water.  This was a technique I used quite a bit while I was out in public and wanted to paint but didn't want to bring a heavy bag of supplies.  After realizing that the ink in my calligraphy pen reactivated with water and the shape of the nib gave my drawings an ever-changing line quality, this became my favorite lightweight method for painting on the go.  I would first carve out the shadows of the figure with ink and paint over the darkest points to give slight depth.  This technique already provided a dark look to the drawings, and I proceeded to give this portrait an even more mysterious demonic appearance.
