Prompt
Using the provided reference sketch as the composition guide, turn it into a highly detailed cinematic dark-fantasy illustration of {argument name="scene subject" default="a warrior confronting a fire-breathing dragon"}. Keep the same basic layout: one warrior in the lower foreground facing one huge winged dragon above. Replace the simple line drawing with realistic epic concept art: the warrior wears battle-worn armor, a torn red cape, and holds a raised sword; the dragon is massive, horned, spiked, with wide leathery wings, clawed feet, glowing eyes, and a torrent of fire blasting from its mouth toward the battlefield. Add a dramatic environment not present in the sketch: burning ruined castle/city, collapsing towers, banners, smoke-filled storm clouds, flying embers, lava-like orange firelight, and jagged black rocks in the foreground. Style should be {argument name="visual style" default="ultra-detailed cinematic fantasy game key art"}, with intense contrast, dynamic perspective from behind the warrior, warm orange flames against dark gray smoke, no UI elements, no sketch lines, no text, no watermark.
