Fotorealistisches Fitnessstudio-Spiegel-Selfie mit Pilates-Reformer

Hyperrealistic modern gym mirror selfie photography, vertical format approx. 4:5, a young adult East Asian woman sits in the center of a black Pilates reformer / megaformer training machine, taking a selfie with her phone toward a large floor-to-ceiling mirror. Using an equivalent phone lens of approx. 28-35mm, the subject is about 0.9-1.3 meters from the mirror, camera position near chest height with a slight downward tilt, composition from the top of the head to below the knees, subject centered in the frame, occupying about 82-88% of the frame height; the left and right sides retain the black handrails and metal frame of the training machine, and the background fully displays a modern Pilates gym, large floor-to-ceiling glass windows, wooden flooring, and neatly arranged equipment. Realistic phone mirror selfie perspective, no fisheye, no obvious background blur. The subject is a young adult East Asian woman, medium-to-small bone structure, shoulders moderate to slightly narrow, upper body noticeably full, natural bust, short and clearly defined waist, wider pelvis and hips, very full and thick upper thighs, overall soft and rounded thighs, tapering down from the knees. Overall a compact natural hourglass proportion: slightly narrow shoulders and back; full upper body; short waist; clear waist-to-hip difference; wide hips; full thighs. Do not generate tall slender models, long waist, narrow hips, thin legs, muscular athletic legs, or "huge butt with stick legs". The subject sits basically facing the mirror, pelvis centered on the training machine, legs extended forward naturally and together, knees close, full thighs occupying a large area in the lower half of the frame. Upper body stays upright but leans slightly to the subject's right side, shoulders relaxed, body forming a natural slight S-curve. Do not sit cross-legged, spread-legged, squat, or stand. The subject raises her left hand holding a pink triple-camera smartphone to the front-left side of her face, phone held vertically, partially covering the left side of her face but retaining most of the outline of both eyes, nose, and mouth. The phone case is low-saturation sakura pink / candy pink, with a circular magnetic ring or circular stand structure on the back, and a thin black lanyard with a few small silver pendants / chain charms hanging below. Fingernails are mainly black nail art. The subject's right arm is raised, elbow bent at about 90 degrees, forearm pointing upward and slightly back, right hand gently resting near the back of the neck / behind the ear, palm naturally relaxed, forming a casual hair-touching or neck-supporting gesture. The sleeve extends fully to near the back of the hand, only a few fingers of the right hand are visible. Do not generate hands on hips or both hands holding the phone. The head turns slightly to the subject's left, gaze directed toward the phone screen / the phone in the mirror, not looking directly at the camera. Lips naturally slightly parted, expression calm, with a slight post-workout tiredness and a lived-in feel, no toothy smile. The subject has deep black short hair, overall length between chin and shoulders, the back hair casually tied into a low loose bun or low ponytail, with many fine damp strands of hair around the forehead and sides of the face. The bangs are not neat blunt bangs, but rather long, messy, wispy bangs and side strands, some strands sticking to the forehead, eye corners, and cheeks, as if slightly dampened by sweat after exercise. A few fine strands also stick to the skin at the nape of the neck. Do not generate a neat bob, thick blunt bangs, long curly hair, or a high ponytail. The face is small, slightly oval-shaped, with a soft jawline, fair skin with a warm undertone. Dark brown almond-shaped eyes, natural double eyelids, thin black eyeliner slightly extended, defined lashes; eyebrows natural and on the thinner side. The nose bridge is small and straight, lips naturally full, nude pink with a rose tint. Cheeks and the tip of the nose carry a slight post-workout pink flush, skin retains natural pores and a subtle sheen of sweat, no plastic smoothing. The neck wears a thin silver chain necklace, with a noticeable silver cross / gothic-style small pendant hanging at the center, resting above the chest. The ears may have a few small silver studs or cartilage piercings, but no exaggerated earrings. The upper body wears a cream white / ivory white fitted long-sleeve athletic top, overall similar to a yoga / Pilates form-fitting sports top. The fabric is matte high-stretch athletic material, conforming to the chest and waist curves. The top has a distinctive structure: the inner layer is a light off-white thin-strap / low round-neck sports camisole-style chest area, and the outer layer is a same-color long-sleeve cover-up structure, creating a clear low U-neck + double-strap visual. The upper chest edge is horizontally low, revealing the collarbone and upper chest; the outer long sleeves start from the shoulders / upper arms, extending very long to the back of the hands with a slight thumb-hole / glove feel. Do not generate a regular crew-neck T-shirt, hoodie, deep V-neck, or loose top. The top is fully fitted from the chest to the waist, with a few fine horizontal creases at the waistline, and the hem extends to near the upper edge of the hips. The color is uniformly warm white, cream white, or very light beige-gray, with no logos, text, or complex patterns. The lower body wears pure black high-waisted fitted ultra-short athletic shorts / Pilates shorts, waistline at or near the natural waist just below the navel, shorts very short, ending not far below the upper thigh. The fabric is matte high-stretch athletic material, tightly hugging the wide hips and full upper thighs. Do not generate a skirt, pleated skirt, long yoga pants, or denim shorts. The subject sits on a black Pilates reformer / megaformer training machine. The center of the machine has a black padded / sliding platform, and the subject sits in the center of the platform; on the left and right sides are thick black metal or rubber handrails, forming a symmetrical curve along the lower half of the frame. Below the legs, black sliding rails, a base plate, support structures, and some springs / connecting mechanisms are visible, but the machine structure remains realistic, not turning into an ordinary chair or treadmill. The background is a modern high-end Pilates studio / gym. The space is very bright, with multiple black Pilates reformer / megaformer machines arranged to the left rear and center, aligned in depth, creating a clear perspective. The floor is light warm-toned wood flooring, with a slight soft reflection on the surface. Near the subject and the machine, a few black supports, ropes, and footrest structures are visible. At the rear of the background is a large floor-to-ceiling glass window, outside is a daytime city street scene, trees, and building outlines, overall slightly softened by the glass and exposure into a pale blue-green tone. Between the windows are light gray or off-white pillars. The ceiling is a modern open gym structure: light gray-white suspended ceiling mixed with exposed structural elements, with many long thin white linear pendant lights / strip lights arranged, extending from the foreground to the background, creating a strong sense of depth and rhythm. The lights emit a soft warm white glow, no industrial black ceiling or nightclub neon. In the right rear of the frame, a black inverted cone floor lamp / equipment column is visible, shaped like a thin pole topped with a black funnel-shaped structure, blending with the background training machines. Do not make it the main visual focus.
