I didn't set out to do anything specific, just began drawing me, drawing... on 24x36" tan paper with conte and colored charcoal pencils... holding them at end of pencil. But with less control the eyes were misplaced at first so kept drawing over them, so they got darkened too much and it suddenly was looking like one of my daughters during sulky teenage years. I felt the head/neck/shoulders were too stiff so loosened everything up further as it spread outward, adding in additional layered positions as well. It was kind of cut short because I had to leave. But I like it.
