In one session of each series of Crealde Urban Sketching classes I pose for students and then have each student in turn pose of 5 minutes. I give a brief lecture on human proportions and how to fit the figure on the page by noting where the head and feet will be planted before starting the sketch.
I also point out that everyone has more tools at their disposal like watercolor and which can be used to throw quick masses o the page. I do a demo showing my process as I sketch one student. My hope is to convey a frenetic approach where the process is part sketching and part juggling the many tools.
After we do a series of sketches of students isolated on the page like this one, we then start ingratiating the figure onto an environment. I often have the students do a sketch on the Crealde campus and then ask them to incorporate their favorite sketches that they did of fellow students so that it seem like the student was sketched while relaxing on the campus. This then also becomes a lesson in sketching multiple figures on the same page and having them work together in perspective.
