A photorealistic cinematic vertical mirror selfie of a young woman in her early twenties, around 20 years old, with fair skin and delicate facial features, standing in a softly illuminated bedroom. She has a slender, softly curving figure and very long, glossy blue-black hair falling past her waist, styled straight with subtle layers, wispy face-framing strands, and dense blunt bangs grazing her eyebrows. Her visible eye is large and dark brown, enhanced by precise black eyeliner, softly blended smoky shadow, and long lashes. The center of her face is partially concealed behind her smartphone, while her visible cheek has a gentle pink flush and her full lips are painted a vivid coral-red. Her expression is calm, composed, and slightly alluring as she looks at the phone screen.
She stands close to a full-length mirror with her torso facing forward and one hip subtly angled outward. One arm hangs straight beside her body, while her other arm is lifted with the elbow bent, holding the phone-and-tripod assembly near her face. She wears a fitted black spaghetti-strap mini dress exactly as shown, featuring narrow shoulder straps, a low rounded scoop neckline, smooth stretch fabric, a body-hugging waist and hips, and a very short straight hem ending at the upper thighs. A long fine silver chain necklace hangs over the neckline, finished with an ornate silver cross pendant at the center of her chest. A faint linear tattoo is visible along her upper arm. Her fingernails are long and dark.
The black smartphone has two prominent rear camera rings and is mounted vertically in a compact black clamp attached to a slim telescoping selfie-stick tripod. A glossy black accessory with a large silver “CD”-shaped emblem sits between the phone and clamp, becoming a strong foreground element and partially obscuring her face and torso. Preserve the authentic mirror dust, tiny specks, mild digital softness, and slightly dreamy low-resolution texture.
The background is a modest bedroom with pale cream walls, a light wooden doorframe along the left edge, dark bedding, scattered soft pink and white plush objects, and indistinct personal items. Use bright diffused indoor lighting with soft skin highlights, minimal shadows, shallow depth of field, a 35mm-equivalent smartphone lens, gentle bloom, muted blacks, creamy highlights, subtle pink undertones, and nostalgic cool-toned cinematic color grading. 9:16.
Tip: the 'shot on smartphone camera' clause is doing the realism here — keep it, swap everything else.
