A striking cinematic poster featuring a desolated castle in ruins, with collapsed walls and broken towers. Majestic mountains loom in the background, and a dense forest surrounds the castle, adding to the eerie ambiance. In the foreground, a massive emerald-green serpent emerges from the castle's debris. It sports a thick, vine-like body, sharp-edged scales, and a Chinese dragon-like head. The serpent's glowing yellow eyes stare intensely, while backward-curving horns adorn its head. Swirling clouds of poisonous vapor escape from its mouth, creating a haunting and captivating atmosphere., poster, cinematic
