This is my Z-Image Lora of the whimsical illustration style.
Prompts should be simple. There is no trigger word for these, just try to use simple prompts:
illustration, woman scientist brewing potions in her laboratory
illustration, chubby grandmother cooking soup in the kitchen
illustration, weird but happy dude working behind a desk in a library
For a crisper look, Ive been using the "flowmatch discrete scheduler" for generating my images:
