My plan is to insert a model occupying the middle part of the Xuan paper. The pose I have in mind is model standing on her feet with arms on her hips. A rather standard pose.
Initially I want to place her next to the model with the raised head. I decided against that after I reassessed the composition. My painting already has a model looking outwards with a half raised poise. I am therefore obliged to leave the area of her gaze empty. In other words an imaginary cone is placed in front of her eyes and nothing should violate that cone. That is restricted airspace. A no fly zone.
I therefore relocate my intended model next to the one with a cover draped on. I have allowed plenty of room for both models to muse and ponder and not get into each other's hair. Literally.
So the face of the model is left out on purpose. I want to leave some ambiguity as to which direction is the model is looking towards. At first I want to have the model looking at the head-half-raised model as if to address her but then I think it would be a little too smug, especially considering the body language.
My standing model has her arms on her hips, conferring a savvy, not easily backing down persona. She might as well be confronting someone outside the group, or being defensive about something.
