Photorealistic Full-Body Mirror Selfie with Identity Lock

Create a highly photorealistic, high-resolution full-body mirror selfie of a young woman in a modern indoor gym using the uploaded reference image with strict identity lock enabled. Her face must be 100% identical to the reference image with absolute preservation of identity. Do not alter facial structure, proportions, bone shape, skin texture, skin tone, eye shape, nose, lips, expression mechanics, age,or any fine facial details. No beauty retouching, no face refinement, no identity blending, and no stylization. The face must be an exact, unmodified match to the reference.
Her hair is {argument name="hair style" default="dark brown, styled in a long, wavy, messy bun with loose strands framing her face"}, appearing natural and realistic. Skin remains natural and realistic, matching the reference precisely.
Her expression is {argument name="expression" default="calm, composed, and slightly focused as she looks at the phone screen during the mirror selfie"}. Maintain a natural, candid demeanor without changing facial expression details.
She stands with one leg slightly forward, holding an orange iPhone smartphone in her right hand for the mirror selfie and a transparent water bottle filled with blue liquid in her left hand.

Outfit details:

Fitted short-sleeve white crop top

White long-sleeve shirt tied around her waist

High-waisted black athletic leggings
White crew socks
White athletic sneakers
Environment: a clean, modern gym featuring large wall mirrors with a visible vertical mirror seam in the frame, treadmills, weight machines, rubber gym flooring, and exercise mats. The background should be clear and realistic, with accurate scale and depth.
Lighting is bright overhead fluorescent gym lighting, providing even, neutral illumination with minimal shadows and no dramatic contrast.
Composition: a casual fitness lifestyle photograph, captured at eye level, with the subject centered in the frame. Emphasize sharp facial detail, realistic clothing textures, accurate reflections, and a clean, modern, casual mood. Apply minimal post-processing, no filters, no style transfer, and maintain strict facial identity lock at all times.
