Futuristic Cybernetic Character Concept

A striking character concept portrait of a 35-year-old male cyborg mechanic with a broad muscular build, weathered skin, and a determined gaze, featuring an exposed intricate biomechanical right arm with visible hydraulics, carbon fiber weave plates, and glowing amber fiber-optic lines, wearing a heavy grease-stained canvas apron over a dark grey techwear jumpsuit, standing inside a dimly lit subterranean workshop filled with hanging mechanical tools, glowing holo-displays, and suspended engine parts, illuminated by a warm key light from a hanging work lamp above mixed with cool blue ambient backlight from holographic screens, highlighting oil smears on his cheek and the polished metallic sheen of his prosthetic arm, captured in a three-quarter torso portrait with a confident crossed-arms pose, shot on a Sony A1 with a 70-200mm f/2.8 GM lens at 105mm, sharp focal plane on his face and cybernetic shoulder, smooth background blur, high detail render, industrial sci-fi aesthetic.
