Sometimes a beautiful model does a beautiful pose which looks for all the world like a model doing a pose. You know it would take almost nothing to turn that pose into tying back her hair or holding onto her hat because the wind is blowing or drawing a sword from from a back sheath. But I'm the only one in the classroom who thinks like that so I have to make these things up on my own. In time I'll have the money to hire models to do the poses I really want but for now I have to work with what I have and what I have are sketches and sometimes photographs.
Working partly from a photo and partly from imagination I put her right arm in a different posture. At first I was going to rest her hand on a barrel, then I gave her a pole instead and then the angle of the pole made me think of a rope, which made me think of a pier.
