The above sketches vary from 2, 5 10 minute poses and different materials. The last 3 are all the same model and I think I have managed more accurately to find the weight and angle of the stances.
Separately I worked on this single piece building up the colour as a way of finding the form of the pose. I like how the torso has come alive in the use of the contours of the marks and have tried hard to keep the essence of the pose and the twist of the body.
Perhaps it is better to over exaggerate the angles in the first place in order not too loose the pose as I work into it.
