Profile / Avatar - Ultra-Wide Angle Bikini Mirror Selfie with Identity Lock

(Vertical 9:16 smartphone aspect ratio). A raw, high-contrast mirror selfie captured with an {argument name="phone model" default="iPhone 17 Pro"} using the 0.5x ultra-wide-angle lens. NO ARTIFICIAL BOKEH. Everything is SHARP and in focus from their eyelashes to the posters on the background wall.
Subject & Identity Locking (CRITICAL):
•Identity 1 ({argument name="subject 1" default="Sydney Sweeney"}): Strictly preserve her exact heart-shaped facial structure, hooded blue eyes, and voluminous blonde hair. Focus on a dominant structural bust volume and substantial, thick-toned leg presence.
•Identity 2 ({argument name="subject 2" default="Billie Eilish"}): Strictly preserve her unique facial structure, sleepy/heavy-lidded eyes, and dark, sleek hair. Focus on her fit, curvy physique and symmetrical structural volume.
•Bio-Fidelity: Render high-fidelity "TrueLens" skin physics: visible micro-pores, natural "satin-finish" glow, and fine peach fuzz catching the lamp light ONLY along the jawlines.
•The Tan Line Factor: Both women feature sharp, high-contrast aesthetic tan lines across their chests and hips, contrasting golden-tanned skin with pale white skin beneath the bikini lines, exactly like the reference.
•Expression: Both are looking into the mirror with a neutral, confident, and slightly indifferent "bedroom eyes" gaze.
Outfit & Physicality:
•Clothing: Both wear matching minimalist Cream/Sand-colored Triangle Bikini Sets.
•Tension: The ultra-thin strings show extreme elastic tension and a vacuum-tight fit, creating realistic physical interaction and "tension lines" where the fabric contours to their fit silhouettes.
•Physics: Realistic skin-to-skin interaction where they stand close together, and skin-to-surface compressionwhere their forms overlap.
Pose & Composition:
•Pose: A classic "fit-check" mirror selfie. Sydney (on the left) and Billie (on the right) are standing side-by-side. They are slightly popping their hips and arching their backs to maximize the high-impact S-curve silhouettes and aggressive hourglass structural tapering at the waist.
•Action: One of them holds a gold-colored iPhone 17 Pro to capture the full-body reflection.
Environment & Social Realism:
•Lighting: Warm, naturalistic indoor lighting from a bedside lamp. The light creates high-contrast highlights on their shoulders and defining shadows that amplify the 3D anatomical depth of their forms.
•Background (SHARP): A detailed, messy "lived-in" bedroom. An unmade bed with grey linens, walls covered in mismatched posters and photos, and a white-framed doorway are all perfectly IN FOCUS. No artificial depth-of-field.
Quality: Raw unedited social-media dump aesthetic, high dynamic range, visible digital grain in the deep shadows, 8k resolution. Single frame.
