Illustrious uses image tags from danbooru for the most part, so it does not use overly wordy descriptions of things like other AI models do.
Essentially start everything with:
absurdres, high quality, masterpiece, very awa, cartoon,Inusen,flat color,<lora:Inusen_Illustrious:1>
then from there, add what you want to see.
For example, for Linda, you describe what she looks like:
1girl,brown hair,long hair,black eyes,large breasts,puffy nipples,makeup,mature woman
Then you add what you want her to wear:
red bikini,high heels,lace belt
Then you can describe an action,pose, and facial expression:
kneeling, squeezing breasts together,smug
You can add location and background objects:
kitchen,chair(object),table(object),plant(object)
From there you can modify and change whatever you want. Adding a male to the scene, I add 1boy as a tag, the describe what the action taking place is. The default male this lora adds is basically Joey, although you can make some changes to the male character like you did with the female one. The model can get confused when two characters are in the scene, so it takes some experimentation to get interesting results. Not every image comes out good. At all.
I recommend diving into the danbooru site to see what kind of tags exist, and try things out. Some tags do not work at all, and some will.
