A better image starts with a clearer prompt.
A practical way to turn a loose idea into a useful visual direction.

Start with the subject
Name the subject before adding adjectives. “A ceramic teapot on a wooden table” gives a model more structure than “beautiful, artistic, highly detailed.” Then describe the action or arrangement you want.
Give the scene a point of view
Add a setting, a lighting direction and a camera distance. A close portrait with soft side light is a different request from an environmental portrait in harsh midday sun. Describe that difference plainly.
Change one thing at a time
Keep a promising seed and change a single part of the prompt. Compare the results at the same aspect ratio. A short, deliberate iteration is easier to learn from than rewriting every parameter.
Use negative prompts sparingly
Describe unwanted elements precisely. A negative prompt can help communicate exclusions, but the behavior depends on the selected model. Keep notes about which settings worked for your actual engine.
