Create an ultra-realistic 8K image, preserving all the facial features of the man in the submitted photo (CRITICAL IDENTITY CRITERION — preserve 100% of the face, hair, and expression). Create a hyper-realistic portrait of a man, casually and relaxedly walking through a grand and luxurious university campus with classical architecture (tall pillars, stone arches, climbing plants, centuries-old trees). He wears a white t-shirt, an open khaki short-sleeved shirt with a subtle wave pattern, loose chino pants, and the latest Nike high-top sneakers, carrying a navy blue corduroy backpack. The scene is lit with warm, natural, and relaxing light, featuring sharp depth of field and high-quality rendering. Add a discreet signature in the lower left corner using a contrasting color: ‘@dayno_ai’. 9:16
