Candid Butterfly-Lit Portrait of a Young Woman

A photorealistic vertical portrait of the young Indian woman with her exact facial identity, curly dark hair, and natural smile from the reference image, sitting in a three-quarter pose on a polished concrete floor. She looks forward with her hands clasped around her bent knees, wearing the identical light blue sleeveless MIDI dress with a subtle split hem and white casual sneakers. A black pendant lamp hangs directly overhead. The grey studio wall background features a prominent, focused circular spotlight that casts clear, natural-looking shadows of various-sized butterflies, precisely as seen in the reference. Natural daylight illuminates the scene with soft highlights and realistic shadows. Shallow depth of field, sharp subject focus, high-resolution photo with authentic skin texture and clothing details. Ultra HD quality. Preserve the original composition, framing, and vertical 3:4 aspect ratio. 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.
