When describing an image that you want to have created, it's important to be clear about any specific details that you want to exclude. For example, if you previously had a picture of a duck created but it wasn't quite right, you might specify that you want the new image to have a complete head, a single bill, and two eyes. You could also describe any specific colors or scenery that you don't want included in the image. For instance, if you don't want the duck to be depicted against a background of blue water or green grass, you can communicate this to the artist or designer working on the image. By providing clear instructions about what you want to exclude from the image, you can help ensure that the final result meets your expectations and accurately reflects your vision.
