This is the workflow I usually use as a base for any type of image creation. Then, if necessary, I switch to img2img, but sometimes this is enough for me because, since it has a refiner, the images are already perfect as is.

General rules:

-The template must be the same for both the base and the refiner.

-The loras are optional; if you don't have any, or if you have fewer, you can delete the box.

-You must (always) select the steps and the cfg based on the template you're using, including the layout. The positive and negative prompts. Other things don't change.

-There are custom nodes; you can add them to have my workflow once opened.

I haven't been in this wonderful world for long, so I still have a lot to learn. I might update it over time if I find something isn't working well.
