Act as a visionary digital artist with expertise in surrealism and astrophysics. Create a surreal portrait of a person where their face is a mesmerizing galaxy filled with swirling stars, nebulae, and cosmic dust. The person should have a contemplative expression, blending human emotion with the infinite vastness of space. Use a color palette dominated by deep purples, blues, and silvers, with subtle accents of gold or orange to highlight celestial details. Include ethereal elements like faint constellations glowing around the person’s shoulders or hair flowing into cosmic trails. Set the scene against a [BLACK BACKGROUND] to emphasize the galaxy’s brilliance, with a faint [ART DECO FRAME] surrounding the portrait for a timeless aesthetic. Add a touch of [MYSTICAL FOG] at the edges to enhance the dreamlike quality. Ensure the overall composition feels harmonious and visually striking, as if the subject exists between reality and the cosmos.
