Gollum lurking in a dense, shadowy forest, his skin glistening with an unsettling sheen, incredibly detailed and photorealistic, illuminated by dynamic, eerie lighting. He embodies an extreme nightmare version, with features that echo the mystical and magical, yet deeply creepy. The art style channels the surreal and biomechanical intricacies of H. R. Giger, the imaginative essence of Jean Ansell, and the vibrant storytelling of Justin Gerard. His eyes glow with a haunting luminescence, as if capturing a pivotal movie scene from an otherworldly film. Gollum contorts through various model positions, showcasing his sinewy, full body, a menacing figure that seems both part of the forest and distinctly alien.
