anime illustration, great quality, best quality, character: frostnova_(arknights). A medium shot from a low angle captures a mysterious girl resembling a shooting star in a vast night sky background filled with twinkling stars, distant galaxies, and subtle nebulae glowing in deep blues and purples. She stands centrally with ethereal poise, her long hair cascading down her back with tips fading to indigo, framing her sharp, cold heterochromatic eyes—one piercing blue, the other vivid yellow—gazing intensely at the viewer. She wears an unusual, never-before-seen outfit: a form-fitting white coat with intricate silver embroidery, open at the front revealing a black inner layer, paired with sleek black gloves and subtle metallic accents catching starlight. Her hands are clasped lightly in front, fingers interlaced with delicate tension. The atmosphere is cosmic and serene, illuminated by soft starlight casting gentle highlights on her hair and clothing, with a starry particle glow and faint lens flare enhancing the otherworldly mood.
