Knight Facing Colossal Cathedral Giant

Cinematic dark fantasy key art in a 16:9 frame. In the foreground left, a lone armored knight stands with his back to the viewer, wearing battered blackened plate armor and a torn [blue] cloak with frayed gold trim, gripping a straight longsword planted point-down in wet stone. Towering over him in the midground center-right is a colossal undead cathedral-like giant with a helmet-like glowing vertical-slit face, exposed ribcage armor, hunched shoulders, dangling arms, draped in heavy moss, roots, chains, and tarnished gold filigree. The scene features exactly two humanoid figures emphasizing massive scale contrast. Setting is a ruined gothic cathedral courtyard at stormy night with low fog, floating ash particles, tiny torch flames, and wet reflective ground, flanked by a tilted spire on the far left, a broken arched bridge in the middle-left background, and a ruined cathedral arch tower on the far right. Dramatic low-angle composition with chiaroscuro lighting, where a red-black storm glow on the left fades into cold blue moonlight on the right.
