close-up illustraition portrait of a grimdark sci-fi figure wearing a heavily modified gas mask with two large glowing toxic green circular lenses emitting an eerie light. The mask is covered in intricate religious symbols, crosses, and occult engravings. Numerous tangled black wires, cables, and dripping tubes hang messily from the mask and headpiece, creating a chaotic cybernetic look. Messy dark hair is visible above the mask. The figure wears a dark, worn hooded jacket. In front of the chest, slightly below the mask level, a pair of hands holds up an intricate floating cubic relic that glows with faint inner light, detailed mechanical patterns and sacred geometry on the cube. Dark, oppressive atmosphere with strong green glow reflecting on wet surfaces and metallic parts, heavy volumetric fog, floating particles, and cinematic rim lighting. Grimdark sci-fi aesthetic, highly detailed painterly style, moody and menacing mood
