沉思的草地肖像提示（身份保留）

Use the uploaded image to preserve exact facial features, hairstyle, and contemplative expression. A young man stands amidst waist-high, dew-covered meadow grass, wearing a worn olive green canvas jacket over a dark t-shirt. Thick morning mist blankets the background fields and obscures distant tree lines, creating a soft, diffused white light. Shallow depth of field focuses sharply on his face and the texture of the jacket. Ultra-realistic, film grain texture, desaturated cool earthy tones.
