A lone warrior in full battle gear sits upon a monstrous, skeletal horse amidst a desolate landscape ravaged by famine, its intricate armor glistening under cinematic lighting. Shadows stretch ominously, enhancing the horror of the scene, captured in exquisite, photorealistic detail. The air is charged with a sense of impending doom, heightened by the 8k resolution and hyperrealistic textures, brought to life by octane rendering and VFX post-production. RTX ray tracing casts hauntingly realistic shadows, lending depth to the intricate design of both horse and rider. This dystopian tableau, rich in cinematic noise, could have leapt from the pages of an ArtStation or CGSociety masterpiece.
