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. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
