The prompt "x-shaped pupils" sometimes results in blurry or warped pupils and may struggle with different pupil colors. It's trained mostly on women's eyes but works fine for men as well. This LoRA gives clean X shapes and allows the user to prompt for white, red, black, etc. X's. (If you don't specify the color, it will usually default to white pupils.)

Best used at lower weights—don't go over 0.5 or so. Use prompt detailed_eyes for more interesting iris shapes.
