Ink-Etched Family Portrait

A black-and-white hand-drawn family portrait in the style of detailed pen-and-ink crosshatching on textured white paper, showing 4 people seated closely together in a casual candid composition. On the left, an adult man in a dark baseball cap worn backward and a dark T-shirt leans into the frame, with a crossbody sling bag worn across his chest and visible zipper details. On the right, an adult woman with curly hair tied up in a loose high bun wears a light T-shirt with large collegiate block letters reading CITY. In the center are 2 young children sitting close together, both with short curly hair and matching light-colored T-shirts printed all over with strawberries. The child on the left leans inward with one arm crossing the other child, and the child on the right tilts their head slightly upward. The adults frame the children protectively, creating a warm family snapshot feeling. Render the whole image as a monochrome etched illustration with dense fine-line hatching, engraved shadows, crisp contour lines, and a realistic yet artistic likeness, with no color, no background setting beyond a plain light paper texture, and a vertical portrait crop. 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.
