Wise Old Wizard Portrait in Moonlit Study

A highly detailed fantasy portrait of a wise old wizard with a long white beard and piercing blue eyes. He sits in a dim study filled with ancient books, glowing runes, and a softly glowing crystal orb. His midnight-blue robe is richly embroidered with silver stars and arcane sigils; a tall pointed hat rests on his head. Warm candlelight and cool moonlight sculpt his wrinkles and illuminate his intense blue gaze. Dust motes drift in the air, and a faint magical aura crackles at his fingertips. Painterly digital painting with ultra-high detail, photorealistic textures on skin, beard, and fabric, cinematic lighting, shallow depth of field, rich color palette of golds, blues, and purples.
