Natural Couple Portrait – Casual Black Aesthetic

Create a photorealistic, high-quality casual couple portrait based closely on the reference image. Preserve the same facial features, identity, hairstyle, skin tone, body proportions, expressions, and natural appearance of both people. The couple is standing close together indoors, facing the camera with a relaxed and confident expression. The woman has long, naturally wavy dark-brown hair and wears a simple black sleeveless crop top with black casual bottoms. The man has thick textured black hair, light beard and moustache, and wears a fitted black sleeveless vest with black casual bottoms and a simple silver chain necklace. Use soft natural indoor daylight, a neutral light-gray/cream wall background, realistic shadows, authentic skin texture, detailed hair strands, natural clothing fabric, and an unposed smartphone-photography feel. Keep the composition vertical, waist-up/full upper-body, with both subjects clearly visible and naturally positioned close together.
