光るクリスタルの紋章を持つ天上エルフ貴族の肖像

Celestial elf noble, youthful male elf with refined aristocratic features, smooth pale porcelain skin, sharp almond-shaped icy blue eyes glowing softly with magic. Short layered silver-white hair, slightly tousled, framing the face with elegant symmetry. A small crystalline sigil embedded at the center of the forehead, emitting faint blue light. Calm, composed, noble expression. Wearing an elegant white and ice-silver ceremonial robe with layered flowing fabric, tailored like high elven court attire. Ornate crystalline armor accents on the shoulders and chest, sculpted from translucent ice-like crystal with glowing blue cores. A radiant crystal gem set at the heart of the chest piece, softly illuminating the robe. Subtle mist and ethereal smoke swirl around him, forming a faint circular halo of light behind the head. Soft celestial lighting with cool blue highlights and gentle shadows, shallow depth of field, divine fantasy atmosphere, ultra-detailed, high realism, ethereal elven royalty aesthetic, 4K quality.
