Hi Christina! The good thing is — you can always choose different sets of your favourite images over and over again with the same style tuner to create different codes. You can literally play around and generate a ton of codes and you can try them out to see which one works best in your new MJ jobs!
If only 1 or 2 of the images you like in the images the style tuner shows you, you can pick only those. The recommendation is choosing 5-10, but any number works. Choose only those you really like.
Also, is the “nature” of the prompt you used to create the style tuner page aligned with the nature of the prompts of the new jobs you created with the code? Say, it’s better to use a photorealistic prompt to create the style tuner if you usually like to create photorealistic images.
Hope that helps!
