Mystical Wizard Portrait with Starry Background

Picture a middle-aged wizard with a scruffy beard and wild, expressive hair, reminiscent of Vincent Van Gogh's self-portraits. He wears a flowing blue robe adorned with intricate silver patterns that shimmer faintly, suggesting magical properties. His eyes are bright and intense, reflecting wisdom and eccentricity. The background might be a starry night sky, enhancing the mystical atmosphere.
