This Cave Mech's Core Is Keeping a Human Head Alive

In the foreground, unfocused, a male mountaineer lies on the ground facing the towering machine, his arm outstretched, fear plain on his partially visible body. Dominating the frame is a colossal robot built around a silver-and-gold core that churns with glowing, effervescent orange liquid and is studded with orange, shining screens and LEDs. A metallic human head floats inside that liquid — short, black, militia-style hair, smiling as it watches the mountaineer. Six long, muscular, articulated robotic legs, sharp and blade-tipped, drive into the ground and cave walls on either side of him, while seven big, orange-white, glowing spherical eyes mounted on clawed appendages track his every move. The scene unfolds inside a light red, rocky, irregular cave, its walls broken and fissured, light falling strongest on the robot. Digital fantasy artwork with an epic feeling, framed from a super low angle, portrait orientation, tilted.
