Create an ultra-realistic 8K, full-body portrait of a stylish young man using the same person from the uploaded reference image, standing confidently in an outdoor natural environment. He is placed in front of a rich green forest backdrop that is strongly blurred to create a cinematic depth effect. He is wearing a dark forest-green button-up shirt with chest pockets, with the sleeves casually rolled up to his elbows, along with black cargo pants that give a smart-casual, slightly tactical look. His hairstyle and beard must remain exactly the same as in the uploaded person. He is also wearing black sunglasses and a smartwatch on his left wrist. His pose is relaxed and natural, body slightly angled, with his right hand partially inside his pant pocket, and a calm, subtle smile on his face. The lighting is soft and natural, similar to golden hour or gentle overcast daylight. Replace the face with the face from the uploaded person and keep the identity intact. The background should be a lush green forest, heavily blurred to separate the subject from the environment and add depth. The image should be vertically composed in a 9:16 aspect ratio, showing the subject full-length, positioned slightly to the right of the center. Hyper-realistic quality, 8K resolution.
