32k photo-realistic, high definition. Depict Zendaya as "Luminary Valkyrie," a superhero with sleek, luminescent armor that shimmers in shades of deep blue and silver, reflecting her powerful energy manipulation abilities. She has long, flowing white hair and iridescent blue eyes, exuding an aura of calm authority. In the background, a futuristic cityscape glows under a twilight sky filled with floating orbs of light. The setting is high-tech yet organic, with intertwining greenery and shimmering buildings. Use a full-body shot to capture her standing on a rooftop, hands raised as energy swirls around her. Lighting techniques should include dramatic contrasts with soft luminescence, rendered with DeepArt.io and Unreal Engine v6.
