A vibrant, high-definition oil painting of an 18-year-old French medieval female knight, her face clear and strikingly beautiful, with gentle green eyes that meet the viewer's gaze. She has short, golden hair, a perfect figure, and an animated, youthful expression, exuding wisdom and strategy. She rides a horse at full gallop, holding a white and gold fleur-de-lis banner aloft, clad in silver armor and a flowing blue cape. The scene is bathed in a golden hue with fiery accents, featuring strong chiaroscuro and chaotic brushwork, creating an artistic composition. 8K resolution.
