DALL-E 3 PROMPT USED: Generate a digital avatar in the style of a realistic photograph, that is 1024 pixels by 1024 pixels. The avatar should depict a bulldog dressed in a superhero costume, displaying the recognisable attributes of a railroad worker, such as a safety helmet and reflective vest. Despite the usual strength associated with a superhero, the bulldog is crying, adding a touch of emotion to the image. The subject should occupy the full frame of the image, rendered from the shoulders up. The lighting should be sufficient to highlight all the details of the bulldog's appearance and outfit. There should be no text anywhere in the image.
