Do you keep it simple? Just long enough? Go wild with it? How about embeddings, do you also use them?

The more I learn about this, the more I don't understand it. Outside of some basic enhancers (masterpiece, best quality, worst quality, and bad anatomy/hands etc. if I'm generating a human), I don't see any big improvements. Every combination gives different result; some look better, some look worse depending on the seed, sampler, etc. It's basically a matter of taste. Note that I only do illustrations/paintings so the differences might not be much. Do you keep tweaking your prompts or just settle with the prompts you've been using?
