Natural Fitness Mirror Selfie – Casual Gym Look

Create a photorealistic vertical 9:16 fitness mirror-selfie portrait using the uploaded images as visual references. Show the same adult woman in a simple indoor gym/changing-room setting, wearing a light beige fitted athletic crop top with thin straps and loose black track pants with subtle white side stripes. Keep her natural dark hair tied back in a casual ponytail, with a few loose strands and small front braids. Capture a relaxed, candid mirror-selfie moment with natural poses similar to the references: one hand occasionally resting behind the head or on the hip, relaxed facial expression, natural posture and realistic body proportions. Use soft neutral indoor lighting, realistic skin texture, subtle pores and natural imperfections. Keep the gray mirror-room background simple and believable, with the smartphone partially visible in the mirror. Photography style: authentic smartphone photography, natural exposure, realistic skin tones, mild camera noise, subtle lens imperfections, accurate shadows and reflections, unretouched photographic look, realistic fabric texture, no artificial beauty filter, no plastic skin, no exaggerated body proportions, no CGI appearance. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
