Можно дать модели простой вариант:
a grid showing the same [man/woman]'s face in many different emotions
А можно немного усложнить запрос (добавив необходимые детали):
a 4x4 grid showing the same man head and shoulders zoomed in, with different poses and emotions. the man is in his 40s, white, has dark hair, and is wearing a blue modern military dress uniform. photo realistic quality
У Midjourney (первая картинка) получилось что-то в духе 21st Century Schizoid Man
