Pose is object identity
Paint answers “what color is it?” Pose answers “what shape is it?” A wall patch should not have the depth of a standing body. A tabletop object should not be taller than the surrounding clutter. A ceiling detail should follow the ceiling plane instead of hanging downward like a player.
Choose the final location before the final pose. Once the silhouette changes, the visible light and shadow on the body also change, so do the last paint pass after posing—not before.
