Imagine a scene from Norse mythology featuring the Valkyries, the warrior maidens who choose the fallen heroes to bring to Valhalla. Illustrate a group of Valkyries riding their majestic winged horses through the sky. Use a color palette of cool blues and whites, with hints of golden sunlight breaking through the clouds. Show the Valkyries in their armor, with flowing hair and determined expressions, radiating strength and grace. Add a sense of movement and energy to the image, capturing the dynamic flight of the Valkyries.
