Gollum lurking in the twilight forest, skin glistening with an eerie sheen, captured in lifelike detail, illuminated by ethereal, dynamic lighting. The scene evokes an extreme nightmare vision, blending mystical and magical elements with an unsettling creepiness. Imagined through the creative lenses of H. R. Giger, Jean Ansell, and Justin Gerard, its luminescent glow casts haunting shadows. It's as if pulled from a surreal movie scene, showcasing Gollum in varied poses, his full body tensed and twisted, set against the backdrop of the otherworldly landscape.
