Last night we had the same model, with very good posture and not much variety of poses. I’m posting three of my attempts from last night. The 5 minute is quite nice, and I would have liked to work on that pose/angle a bit more. In the 20 minute, the drawing/proportions are a bit off (the breasts should be higher up on her body), but with a bit more time I might have been able to fix that. Doing the 60 minute I experimented a little bit, and was rewarded with some muddiness. I also wasn’t quite sure where the nose was and avoided specifying. On the whole, a decent run.
