Prompt
Generate a realistic portrait of Mark Vonnegut, an American physician, author, and son of Kurt Vonnegut, sitting in a quiet, introspective environment, surrounded by books and medical paraphernalia, with a subtle hint of his experiences with schizophrenia, in a style that blends realism with a touch of warmth and sensitivity, wearing casual, comfortable clothing, with a gentle expression, in a medium close-up shot.
