Low-Key Fashion Portrait Character Swap

Create a hyper-realistic black and white low-key fashion portrait based on the uploaded reference image. Keep the exact same composition, square framing, camera angle, subject placement, upper-body crop, head tilt, shoulder position, body angle, background, lighting direction, shadow placement, contrast, grain texture and overall dark editorial mood. Replace only the original person with the character from the newly uploaded target reference image. 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.
