Here’s a detailed image generation prompt based on the photo: **Prompt:**

A realistic portrait of a young South Asian man in his early 20s with medium-dark skin, short wavy black hair, and a light well-groomed beard and mustache. He is looking off to the right side with a calm, thoughtful expression. He is wearing a dark navy blue long-sleeve button-up shirt with a subtle geometric diamond pattern, sleeves rolled up to the elbows, and a single chest pocket. He is leaning casually with his right arm resting on an old rough stone wall covered in green ivy. Behind him are lush green rolling mountains under a bright clear sky, with a soft natural daylight illuminating the scene. Photorealistic style, sharp focus on the subject, natural outdoor lighting, shallow depth of field.
