You’re right. I tried to create a normal face, using the lip-focused text swap, but it didn’t work. I originally thought it was because the words didn’t match, but now it’s clearly something else.
prompt:
Create an image of a medium shot teenage female with long, wavy black hair, a neutral expression, arched eyebrows, almond-shaped green eyes, a button nose, [The lips are full and balanced, with the upper and lower lips equally plump]. Lightly tanned skin, with freckles, with soft lighting against a dark background.
[The lips are narrow and thin, with both the upper and lower lips lacking fullness]
[The upper lip has two curves that rise higher than usual and meet in the middle, forming a V-like shape.]
[The upper lip has a gentle curve, with the highest point in the middle and it softly slopes towards the corners of the mouth.]
[The lips are round and full, particularly at the center, with a soft and even contour.]

As for the fire image, I think I got lucky. After you posted this, I went back and tested, but it was hard to do it the same way.
