Vintage engraving illustration based on the reference photo. Highly detailed black ink linework, dense parallel hatching and cross-hatching, precise contour engraving lines influenced by classical woodcut and copperplate etching printmaking. Pure monochrome black-and-white palette with intricate line density variation to establish volume and depth. Curved line flow closely following form and structural contours, with any figures depicted fully clothed in modest attire, accented with fine stippling for soft transitions. Baroque master craftsmanship and antique scientific illustration aesthetic. High contrast with clean negative space, hand-engraved texture simulation. Purely line-based shading with no color, no smooth gradients, and no airbrushing.
