underwater engineer 3d model

A gritty industrial deep sea submarine crew member standing in a clean T-pose for a character reference sheet, front and back view, transparent background. The character wears practical retro-industrial underwater workwear instead of a diving suit: heavy waterproof jacket, layered utility clothing, worn cargo pants, steel-toe boots, tool harness, flashlight, analog wrist gauges, radio headset, gloves and emergency rebreather mask attached to the chest harness. The design should feel grounded, functional and believable, inspired by submarine engineers, offshore oil rig workers and deep sea maintenance crews. No futuristic sci-fi armor, no astronaut aesthetics, no bulky diving suit. The outfit should look used, dirty, oil-stained and repaired multiple times. Color palette: dark navy blue, faded military green, rusted metal, worn gray rubber, dirty yellow accents. Style: ultra detailed cinematic concept art, realistic materials, industrial horror atmosphere, subtle retro-futurism, analog
