It's better to be as detailed as possible when explaining a design to an AI art generator, but leave some space for creativity as well. First, make a list of the most important parts of your design, like the style, colors, setting, and theme. If you want to make a logo, for example, you could ask for "a minimalist logo design with a blue and silver mountain, clean lines, and a modern, geometric style." If you want a complicated illustration, describe the composition, lighting, and art medium in depth. For example, "A glowing city skyline at dusk, painted in a neon cyberpunk style with dramatic lighting." The AI will be better able to understand what you mean if you use detailed and exact wording.
