Create a digital painting of Sylvanas Windrunner from World of Warcraft. She is a tall, slender female elf with pale skin and long, flowing white hair. She has glowing, icy blue eyes and sharp features. She is wearing her iconic black and grey armor with intricate silver details, and a dark hooded cloak with tattered edges. She holds a powerful bow in one hand and has a quiver of arrows on her back. She has a determined and fierce expression, as if ready to face any challenge head-on. The background should be a dark and foreboding forest, with wisps of mist floating around her.
