Black-and-gray biomechanical design with orange crackles

A highly detailed and realistic black and gray tattoo of a robotic or mechanical arm extending from the shoulder down to the wrist. The design features intricate mechanical components, such as gears, pistons, and plating, with a focus on shading to create a three-dimensional, metallic appearance. The background incorporates dynamic, jagged lightning or energy-like elements in shades of black and gray, adding a sense of power and movement to the piece. The tattoo covers the entire forearm, blending seamlessly with the natural contours of the arm.
