This was the clothed model at life drawing today in a 20-minute pose. One of the other artists commented on the speed of my drawing. I think it is because I use contour drawing. I learned to draw in this manner from Bill Robles in the 1970's at the Art Center College of Design. He was/is a courtroom artist.
I switched from pencil to a marker for these 20 and 10-minute poses.
These are 2 minute warm-up sketches. I painted the panels with watercolor. I am in the habit of doing the panels because I usually paint the nude. It helps speed up the painting process for quick poses.
