A central cog-like gear is surrounded by intertwining wires, steel tubing, and organic vein-like forms, merging mechanical and anatomical features. Bold outer lines give it structure, while internal components are illustrated with intricate, fine-lined patterns that mimic metal textures and muscle fibers.

Space available for a quote or label along the margin.” in the style of realistic.
