Cinematic horror poster with a unified, immersive background and a strong film-like atmosphere. At the high center of the composition, an ultra-realistic face of a decayed zombie head wearing a gas mask. The gas mask is worn, scratched, and aged, made of dark rubber and metal elements. Portions of decayed skin are visible around the edges of the mask: pale, cracked flesh, deep scars, and damaged textures. Dried blood stains appear around the mask straps and along the jawline, subtly integrated without excess. The mask straps are stretched and frayed, digging into rotting skin, enhancing realism. The background is fully unified and cinematic, forming a continuous dark environment from top to bottom. A foggy, post-apocalyptic forest surrounds the subject, with tall, thin trees fading into heavy mist. There is no visible separation between foreground and background, creating depth through atmospheric perspective only. In the mid-to-background, a distant horde of humanoid zombies emerges slowly through the fog. Their silhouettes are partially obscured, ghost-like, and desaturated, reinforcing scale and tension without overpowering the central subject. Lighting is low-key and cinematic: soft volumetric fog, strong directional shadows, subtle rim lighting outlining the gas mask and head. The color grading is dark and desaturated, dominated by cold greens, bluish greys, and muted earth tones, inspired by modern horror and post-apocalyptic cinema.
