Over the summer at BYU I took a gesture drawing class from Ryan Woodward. Like most figure drawing classes, we did some of the normal stuff where we just drew the models in at most 5-10 minutes per pose.
There were also a few days that we brought in costumes for the models to wear. The ranger cloak someone brought in ended up as one of the most popular choice.
The most interesting part of the class was when we were told to exaggerate the proportions of the model in various ways.
The last two we had to draw a weird shape and then draw the model within that shape.
