DALL-E 3 PROMPT USED: Create a 1024 pixels by 1024 pixels avatar of a dog from the shoulders up, styled like a high school yearbook photo. The dog carries the aura of an environmental engineer, implying an individual who works on projects to solve environmental problems. The dog is holding a telephone to its ear, a quirky feature of the portrait. Ensure that the image is well-lit and there is no issue with visibility to appreciate all the details about the persona and its outfit. The avatar should be realistic and occupy the entire space, observing no text on the image.
