I started my figure drawing class and it turned out to be a lot of fun. We did quite a few two minute poses to learn gesture drawing.
Here are the steps.
1) Create a stick or wire drawing
2) Men's bodies are pickle shaped and women are peanut shapes. So.. draw the correct shape inside the wire figure's body.
3) Find the mid line the body.
4) Draw in the flesh.
I think you need to be there to understand.
I kept repeating it over and over, again, as I drew. Wire, pickle, mid line and flesh. It was fun because of the model knew how to contort his body making it difficult to draw the wire drawings. Great stuff.
Here are the last two of my drawing. They were 5 minute gestures.
