Photorealistic summer portrait of a stylish man standing by a calm lake with distant green hills, three-quarter length, relaxed, confident pose with hands in pockets and head turned to the left, warm golden-hour diffused light, soft rim lighting. He wears an olive-green linen button-up shirt, slightly unbuttoned, a cream sweater casually draped over his shoulders, and off-white tailored trousers; visible linen weave, realistic fabric folds, natural creases, and stitching detail. Short dark hair, neatly trimmed beard, round tortoiseshell sunglasses with subtle reflections, wristwatch with green dial and metal bracelet. Soft bokeh background, gentle atmospheric haze over mountains, muted earthy color palette (olive, cream, warm tan, soft blue-gray). High-resolution, ultra-detailed skin texture and facial hair, natural pores, realistic shadows and specular highlights, film-like grain, cinematic composition, shallow depth of field, 85mm portrait feel, slightly desaturated vintage color grading, balanced contrast, photoreal, optimized for compact high-quality generative model.
