Here’s a quick warm-up sketch I did at life drawing last week at Swansea Print Workshop. After this I worked on a portrait study for an hour, but I find I need to have a quick scribble to start with, to get used to the model and pose before committing myself to a longer study.
Although it was done quickly, I really like the immediacy of it. I find that when I tell myself that something is just a warm-up or a practice, I am much freer and less inhibited in my approach.
I worked onto my Samsung Galaxy Note 8 tablet with a free Markers app, sometimes with a stylus and sometimes with my finger.
