DALL-E 3 PROMPT USED: Create a highly detailed and realistic portrait of a lion, depicted as a dentist. This fun yet imaginative avatar should portray the lion from the shoulders up, as you'd see in a yearbook photo. The lion should be smiling, indicating a friendly demeanor, which is essential for a dentist profession. The image should have proper lighting to highlight all the intricate details from the texture of the fur to the sparkle in the eyes and the dentist attire. The size of the image will be precisely 1024 pixels by 1024 pixels with the portrait filling the whole canvas.
