Knight Facing Cathedral Giant

Create a dark fantasy cinematic key art scene in an ultra-wide 16:9 frame. In the foreground left, show one lone armored knight, back turned toward the viewer, wearing battered blackened plate armor and a torn deep {argument name="cape color" default="blue"} cloak with gold frayed trim, gripping a long straight sword planted point-down in the wet stone ground. In the midground and center-right, show one colossal undead cathedral-like giant towering over the knight, with a helmet-like vertical slitted glowing face, exposed ribcage armor, massive hunched shoulders, long dangling arms, thick legs, and heavy strands of moss, roots, chains, and tarnished gold filigree hanging from its body. The scene contains exactly two humanoid figures: the small knight and the enormous giant. Surround them with exactly three prominent ruined gothic structures: a tall tilted spire on the far left edge, a broken arched bridge behind the knight in the middle-left background, and a dark ruined cathedral arch tower on the far right. Set the environment in a ruined medieval city or cathedral courtyard under a stormy night sky, with low fog, ash particles, scattered tiny torch flames, wet reflective stone, and a red-black storm glow on the left fading into cold blue moonlight on the right. Use {argument name="visual style" default="grimdark photorealistic fantasy concept art"}, extremely detailed armor, monumental scale, high contrast chiaroscuro lighting, dramatic low camera angle, atmospheric haze, sharp focal detail on the knight and giant, no text, no logos, no modern objects.
