Bioluminescent Elven Archmage Portrait

An intricate character portrait of a dignified elder elven archmage in her late six-hundreds with silver-braided hair falling gracefully over sculpted cheekbones, deep violet eyes brimming with centuries of arcane knowledge, and subtle glowing luminous runes etched gently across her temples, wearing high-collared midnight blue silk robes embroidered with shimmering silver constellations and obsidian pauldrons that catch specular reflections, holding a polished star-metal staff topped with an orb of swirling blue plasma that casts soft ambient indigo light, standing inside an ancient ruined observatory under a breathtaking starry night sky with a giant shattered moon hanging in the background, surrounded by floating ancient grimoires and dust motes suspended in magical energy, lit by dramatic rim light from the celestial sky paired with warm magical glow from the staff casting soft violet and teal highlights onto her weathered yet ethereal skin, her expression calm, regal, and quietly powerful as she raises one finger to command a small hovering wisp of starlight, captured in a tight waist-up shot utilizing an 85mm prime lens at f/1.4 for an extremely shallow depth of field that smoothly blurs the celestial observatory behind her into creamy bokeh, rendered with hyperrealistic digital painting textures, cinematic color grading with rich deep blues and radiant magentas, subtle volumetric rays, 8k resolution character concept art style, evocative of high fantasy epic storytelling, conveying a serene sense of cosmic mastery and timeless magic.
