A towering, grotesque kaiju-like monster made of rotting flesh, vines and algae stomps through a devastated urban canyon, its gaping maw lined with jagged teeth dripping dark saliva, bulbous infected eyes and tangled roots hanging from hunched shoulders; looming over crumbling skyscrapers, rusted metal, shattered glass and scattered corpses. Foreground: a small squad of hazmat-clad survivors with backpacks and rifles stand in awe and dread, silhouetted against the creature, gritty boots on mud and debris. Moody overcast sky with drifting smoke and circling birds, volumetric light shafts, muted sickly greens, browns and ash tones, wet glistening textures, high-detail skin pores, torn flesh, slime, frayed fabric. Cinematic low-angle wide shot, extreme scale, deep depth of field, dramatic rim lighting, high-resolution photorealistic concept art, intense atmosphere, epic horror tension.
