Terrifying anthropomorphic zombie fly in a post-apocalyptic landscape

Terrifying anthropomorphic zombie fly in a post-apocalyptic landscape. The creature stands upright, with decaying insect flesh, glowing red compound eyes, torn wings, and sharp, dirty claws. It wears remnants of tattered human clothes and its mandibles drip with slime. The background is a ruined city in flames, with dark clouds, broken buildings, and radioactive green mist. Cinematic horror vibe.
