Astrid stands in a heroic pose, her fur-lined cloak clinging to her slim frame. Her long, golden braid hanging down her back reaches nearly to her ankles. She holds her spear firmly in her right hand, her left arm gripping a polished shield of bronze. Her face is serious and resolute, her blue eyes glittering with determination. Behind her looms a large dragon, emerald scales gleaming beneath its vibrant red wings. How to bring this scene to life? Start with Astrid's cloak, draping its deep brown over her figure. Shade around her eyes to emphasize their intensity. For the dragon, create a range of greens and yellows, leaving patches of white at its neck. Paint the wings a brilliant scarlet, giving them an air of power and majesty. Finally, finish it all off with some metallic touches - black on the spear and shield, and silver on the dragon's teeth and claws.
