Prompt
Create a realistic portrait of Harold Hongju Koh, a middle-aged Asian American man with a dignified expression, wearing a formal suit and tie, likely in a law-related setting. He should be depicted with a slight smile, conveying a sense of authority and warmth. The background could include subtle hints of his academic and professional affiliations, such as a Yale Law School or U.S. Department of State seal, or a bookshelf with titles related to international law and human rights. The style should be professional and photorealistic.
