Chevalier squelettique colossal affrontant une mage dans une arène antique

Epic dynamic battle scene in a grand ancient colosseum arena. A gigantic colossal skeletal knight in broken ancient armor, with glowing blue eyes, in an aggressive attacking pose, mid-swing of a massive rusty greatsword towards a tiny mage, raising a huge tower shield. Opposing him, a small but determined golden-robed mage, holding a simple wooden staff that erupts with brilliant holy light, conjuring a intricate golden magical shield with his free hand to parry the blow. Dramatic low angle shot emphasizing the size difference. The colossal arena is bathed in a dramatic crimson red light, from a magical barrier or sunset. The stands are filled with thousands of roaring, silhouetted spectators. Volumetric light, dust particles in the air. Style of vintage fantasy book illustration, heavy inking, strong contrasts, textured canvas, retro art. Color palette dominated by deep reds, crimson, black, with contrasting gold and bright blue.
