Some of these drawings are from life - meaning I drew the person who was present in the studio. For this, I visit a local studio and draw as part of a group, for set periods of time. The time periods are normally 10 to 25 minutes with some quicker 'warm up' drawings at the start.
Other images are drawn during online drawing sessions broadcast digitally around the world from various countries. In a similar way, the poses are short, and relatively quick.
I usually commit the line, to the paper, without making corrections. Rather than erase lines during the process I sometimes correct the figure drawings in a post production process. But mostly I just recycle them if they look wrong. So the drawings are quite fresh and energetic.
