Subject
Name the main thing clearly. Add only the details that change its form, material or posture.
Prompt guide
Make each part of the prompt deliberate.
A useful prompt gives the image a subject, a place, a source of light and a clear finish. Treat these as choices, not a formula.
Setting
Place the subject in a specific environment. Describe the space, distance and surrounding objects that matter.
Light
Describe the light by its direction, softness and source. This gives the scene a deliberate sense of depth.
Finish
Close with the visual treatment you want, such as a photograph, a print or a clean digital illustration.
