Generate a highly photorealistic full body portrait of a handsome clean shaven Indian boy aged approximately 18 to 23 years portraying Krishna during a traditional Janmashtami celebration. Give him an attractive youthful appearance with naturally styled thick black hair, expressive dark eyes, clear skin, a defined jawline, balanced facial proportions, and a bright but natural smile. He wears a vibrant yellow dhoti, royal blue silk stole, layered pearl necklaces, subtle golden bracelets, and an elegant Krishna mukut decorated with realistic peacock feathers. He is captured while playing a traditional bamboo bansuri, with the flute positioned horizontally at his lips and his fingers naturally placed over the finger holes as if performing a melody. The flute must be approximately 1 foot long, slim, straight, cylindrical, natural bamboo, with rounded ends, a small blowing opening, and multiple small circular finger holes. Keep the flute realistic, simple, and correctly proportioned to the subject. Do not turn it into an oversized decorative instrument. His face should remain clearly visible and brightly illuminated with soft frontal portrait lighting, while his eyes look naturally toward the camera and his smile remains gentle around the flute. Surround him with an authentic Janmashtami setting featuring a decorated Bal Krishna jhula, marigold garlands, jasmine flowers, brass diyas, flower petals, traditional rangoli, and warm fairy lights. Capture lifelike skin texture, realistic hair, detailed clothing embroidery, natural hands, authentic jewelry, realistic bamboo texture, cinematic depth of field, professional DSLR photography, natural festive colors, and ultra detailed 8K photorealism.
