Create an ultra-realistic cinematic portrait of a young man standing on a concrete lakeside embankment, viewed mostly from behind in a relaxed pose with both hands in his pockets, looking toward the calm blue-gray water. He has naturally curly/wavy dark hair and wears stylish black sunglasses, a premium loose textured beige/taupe button-up shirt with sleeves slightly rolled, relaxed-fit white trousers, and clean white sneakers.
