The prompt and source image define what the generator should prioritize. Clear screen-layout instructions are just as important as the chosen art style.
Building the Subject and Visual Direction
For text to image, the prompt establishes the main subject, supporting elements, palette, lighting, texture, and illustration style. A focused description gives the generator a clearer hierarchy than a long list of unrelated style words.
For image to image, the uploaded file supplies visible reference information. Details that are clear, well lit, and large enough to inspect are easier to carry into the new result than details hidden by blur, heavy filters, cropping, or visual clutter.
Planning the Composition Around the Screen
A wallpaper still needs to work behind interface elements. Describe where the main subject should appear and which area should contain fewer details. For example, a phone lock screen may need open space near the upper center, while a desktop background may need a calmer area on the left for files and shortcuts.
