Style keywords divide neatly into two groups: words that name a real, visually distinct thing, and words that describe how you feel about a picture. The first group changes the output. The second group is decoration on your prompt, and it is remarkable how much of a typical prompt belongs to it.

The Test Is Whether It Names Something

“Watercolour” works because watercolour has physical properties — bleeding edges, visible paper, transparent layers. “Stunning” works on nothing, because nothing about a stunning image is visually consistent. Between them sit words like “cinematic”, which do something, but something vague: usually wider framing, cooler shadows, a certain contrast. Fine as a nudge, useless as a specification.

So before you add a style word, ask whether a person could look at two images and reliably say which one has it. Charcoal sketch, passes. Stained glass, passes. Blueprint, passes. Epic, breathtaking, beautiful — none of them pass, and none of them earn the space they take up.

Medium is the strongest style lever available. Naming a physical way an image could have been made — oil paint, linocut, pencil, gouache, 35mm film, clay model — changes texture, edges and colour behaviour all at once, and it does so consistently. If a prompt has room for exactly one style word, make it a medium.

Eras and Traditions Beat Adjectives

After medium, the useful words are the ones that point at a recognisable body of work: mid-century poster design, Art Nouveau, Soviet constructivist print, 1970s science fiction paperback cover. These carry palette, composition and subject conventions bundled together, which is far more information than any adjective delivers.

Naming a specific living artist is a different matter and worth thinking about before you do it. Naming a movement or period gets you most of the same visual territory without borrowing someone’s individual signature.

Two or Three, Not Ten

Style words interfere with each other. Watercolour and photorealistic pull in opposite directions, and the model resolves the conflict by half-committing to both — which is how you get that muddy, in-between look that belongs to no medium at all. Pick a medium, add at most one or two supporting terms, and stop.

The most reliable way to build a keyword set is to test one word at a time against a fixed prompt. Same subject, same setting, change only the style term. Twenty minutes of that will tell you more about which words actually move the image than any list you can copy.
