You start with a prompt that “almost works”, but you need:
Write one sentence that describes only the subject:
a black cat sitting on a windowsill
Pick one style direction:
watercolor illustration
soft morning light, calm mood
close-up, shallow depth of field
minimal background, no text, aspect ratio 1:1
If you already have a reference image, Image to Prompt can help you preserve what matters:
Then you can edit just one dimension at a time.
