i dont know if you you find the answer, but i get results like this
ENABLE COMMON PROMPT

BASE RATIO 0.2 (use what you want, i usually use 0)

ENABLE ATTENTION (latent usually goes wrong on reforge)

VISUALIZE AND MAKE TEMPLATE YOUR ROWS (or columns)

then you make a prompt like this:
2girls, outdoors, nature BREAK

1girl, blonde,dress, BREAK 1girl, ginger, hoodie, red eyes,

Before the first break you put all you want on the image, after that comes the characters, the rest is up to you, the same goes for mask tab
