One of my fave models came back to life drawing, and she was a fresh breath of air. She’s pretty, but more importantly, she knows how to run a session. From the start she gives you some nice gestures to warm up with, and as poses get longer, she adjusts to keep them in her range- that being something she can realistically hold well. She was obviously tired, and there were times she drifted, but even then, not as much as others have done recently; and more importantly she mixed up the poses to keep them challenging.
Here are the first few warm up sketches, these were 5 min.
This was a 10 min., and I spent most of it doing a head sketch.
