DALL-E 3 PROMPT USED: Create a 1024x1024 pixel avatar of a cat in an 8-bit pixel style. The cat is a veterinarian, hence it should be wearing appropriate outfit like a white coat. Additionally, the cat has tattoos, which add unique flair to its character. The portrait should feature the cat from the shoulders up, occupying the whole image frame for full effect. There must be no text anywhere on the image. Make sure the image has proper lighting to showcase all the details including the tattoos and the clothing.
