A powerful technique for creating more expressive portraits in Midjourney is the use of writing prompts in portrait photography. To create a beautiful portrait in Midjourney, writing prompts can range from simple to complex. I recently came across a reddit post. Archi7 managed to create some incredibly great portraits. The nice thing about it is that he also wrote the prompts. I tried it out right away. Here you can see which prompts he used and how they turned out.
