Hyperrealistic Macro Eye Detail

Extreme macro close-up of the same woman from the reference image, keeping her exact identity, eye_color, skin_type and hair_color. Tight crop on one eye and eyebrow, straight-on eye-level angle, serene expression. Hyperrealistic detail: pale blue iris with fine striations and a soft catchlight, natural sparse lashes, fine crepey eyelid texture, deep natural wrinkles and age spots, a soft silver brow. Soft even studio beauty light, pale gray background, 100mm macro, razor sharp, photorealistic, not airbrushed, no text.
