"prompt": "A cinematic fantasy battle scene showing two massive stone-skinned giants with glowing eyes towering over the landscape, both roaring and spitting streams of fire from their mouths. The flames light up the misty air as they move their heads in fury. A brave warrior stands on a rocky cliff below, holding up his shield to protect himself from the incoming flames, his cape fluttering in the intense heat and wind. The sky burns orange with fire reflections, smoke and sparks fill the air, camera moves dramatically around the scene, ultra-realistic lighting, high-detail 4K fantasy tone, epic and powerful atmosphere.",
