ultra realistic 4k picture, there is a crocodile dressed in a white doctor's coat, wearing a medical mask and holding a magnifying glass, as if ready to conduct a dental examination. Its teeth are bright white and sharp, and around it are scattered dental instruments: a mirror, forceps, and a dental lamp. The crocodile is smiling, showing its sharp teeth, while its eyes convey friendliness and professionalism. On the wall behind it hangs a diploma in dentistry, and next to it is a chair for the patient. --s 1000 --v 6.0
