Mecha Articulation Test Hangar

Cinematic wide Japanese robot-anime concept illustration of a massive humanoid combat mecha undergoing maintenance and articulation testing inside a dark industrial hangar. The towering white and gunmetal-gray armored robot stands upright in a launch bay, featuring bulky shoulder armor, angular chest plates, segmented waist armor, heavy forearms, large mechanical hands, thick leg armor, broad feet, a helmet-like head with a narrow visor, a forehead crest, and antenna fins. Intricate details include exposed pistons, hydraulic joints, dangling cables, panel seams, scratches, grime, orange warning lights, and subtle decal markings. The vertical hangar is filled with steel gantries, catwalks, heavy cranes, articulated support arms clamping the robot's torso and legs, maintenance rails, ladders, and overhead strip lighting. Exactly 6 technicians in white helmets and pale maintenance jumpsuits provide scale: 1 on the upper-left catwalk, 1 at a lower-left console, 2 together on the right mid-level catwalk, 1 at the foreground-right terminal facing away with "[A/1]" printed on their back, and 1 near the central base platform. Visible environmental signage includes: upper-left gantry stenciled with "[SC-02]" and smaller "M-BLOCK"; right wall stenciled with "A-60", "SUBJECT : [A/1]", and "[ARTICULATION TEST]"; and a foreground monitor displaying "STATUS", "[ARTICULATION TEST]", large "[A/1]", and vertical readout lines "E-01", "E-02", "E-03", "E-04", "E-05". Style: Highly detailed hand-painted mecha anime art style, gritty sci-fi military aesthetic, teal-gray shadows with warm amber accent lighting, dense linework, dramatic low-angle shot, sharp focus.
