There is always some cherry-picking, but prompt engineering is an art per se, you become better and better working on it.
I just started this experiment

and spent A LOT of hours and patience to become good at it. Now I'm very proud of my results and I'm working on doing better.
It's a bit risky to invest too much time because every generator is different and they change the underlying model frequently (see the beta of MidJourney yesterday), but if you do it for passion or curiosity there is no problem.
Now I'm experimenting with a local installation of Stable Diffusion (well, not really "local" because I have an old computer) and the prompt is only one of the things you can tweak. There are num_inference_steps, guidance_scale and other parameters.
