Cozy Nighttime Portrait of Young Woman

Create an ultra-realistic cozy nighttime portrait of a beautiful young adult woman with long, thick, naturally wavy dark black hair, soft feminine facial features, expressive dark eyes, natural glowing skin, and minimal makeup. She is wearing an oversized loose black sweatshirt. Capture intimate candid moments in a warm, dimly lit bedroom with soft lamp lighting, creating a cozy moody atmosphere. Include natural poses such as lying on a pillow, taking a mirror selfie with a black smartphone, gently covering her mouth with her sweatshirt sleeve, and a close-up facial portrait. Photorealistic skin texture, realistic hair strands, subtle shadows, warm cinematic lighting, authentic smartphone-camera look, slightly grainy low-light photography, soft focus background, natural imperfections, 4K detail, vertical Instagram aesthetic.
