Biomechanical Engine

Description

A realistic biomechanical forearm tattoo showing exposed pistons, cylinders and metallic struts beneath torn skin. Black-and-grey machinery contrasts with red, flesh-like shading and sinew wraps, creating a 3D 'skin-ripped' effect. Often chosen to represent resilience, inner strength or a fusion of human and machine—a cyborg aesthetic symbolizing endurance and toughness.
