I always try to include as much detail as possible with my posts, no matter what program I make them in. Just good manners to help people asking "what is that awesome outfit/prop/hairstyle/background, etc. you used?" or "How did you get such-and-such an effect out of Daz/Poser/Photoshop/whatever?" So yeah, I can see what you're getting at with listing our prompts. Because it's not all just three words, one click and presto! instant masterpiece. It really does take a lot to keep it from running off the rails. Case in point:

Prompt used: cushion, deep purple, velvet, realistic, finely detailed, highly detailed, dramatic, action, photo, cinematic, soft lighting, high quality

Negative prompt used (for things you don't want in the image): out of frame, off center, background, humans, people, animals, man, male, female, woman

Resulting Stable Diffusion render: 

Obviously NOT the specifically requested purple cushion. Five out of six renders in the batch made with this prompt resulted in similar cute girls in fancy purple dress; the odd one out was an empty bedroom scene that had a couple of gold cushions and a purple bedspread. Nice, but not what I was aiming for. So much for the "Make Art" button they're calling this AI thing. I'd have an easier job herding cats.
