I know there is a lot of modes of Chloe Grace Moretz, I'm publishing mine just because I don't really like the others, most of them are not really flexible, sometimes it's just a matter of taste.

Usage:

keyword: chloegm

I got pretty good results with Yamer's Realistic XL, but any realistic model should work.

at CFG 7, 50 steps, strength 1 produce good results, negative prompt is not needed.

Have fun!
