Colossal Oceanic Mecha Energy Core Concept

Full prompt

Extreme low-angle upward close-up of a colossal mecha's chest core, half-submerged in the nocturnal ocean while towering miles into turbulent storm clouds. The massive chest armor opens up to reveal a glowing central energy core radiating cosmic currents, surrounded by thick hydraulic conduits, barbed layered plating, molten red conduits, and pulsating blue indicator lights. Rendered in matte space-grey metal with micro-textured surfaces, volumetric mist, and grand scale, 9:16 aspect ratio.
