We wrote down words we associated / believed the pose could be about for 1minute and then drew. Doing this we could think about each part of the body and how it affected the gesture. I like the drawing in the middle ass the model exaggerate the turn of the face and the arm –
The curve of the back, the face inside the arms (even though the arms are hinted we feel them extending out). The weight distribution of the legs.
The many flow lines of this sheet – my favourites are those with the arm extended as the lines I’ve used just capture the direction of the arms and leads our eyes up.
