A close-up of a heavily rusted Iron Man helmet, its iconic features lying abandoned on the ground in a dense, overgrown jungle. Thick vines and sprawling roots entwine themselves around the suit, with patches of moss and lush foliage partially obscuring its surface. The once-vibrant red and gold armor now bears the marks of time, its paint chipped and marred by deep rust marks, giving it an ancient, weathered appearance. The arc reactor at the center of the chest emits a weak, intermittent glow, its light struggling to remain visible through the encroaching decay. The jungle floor is a tapestry of damp earth and scattered fallen leaves, with a soft mist rising in the background, adding layers to the mysterious scene. Diffused sunlight filters delicately through the dense canopy above, casting intricate, eerie shadows upon the forgotten relic of technology. Cinematic, hyper-realistic with meticulous detail, the image conveys a sense of both nostalgia and mystery, rendered with octane precision at 8k resolution.
