Create a vibrant and mystical party flyer featuring both Libra and Scorpio symbols. Include the balanced scales of Libra and the striking scorpion of Scorpio in a harmonious blend. Integrate surreal elements like dreamlike landscapes, swirling cosmic patterns, and floating orbs. Incorporate sacred geometry, such as intricate mandalas or fractals, to add depth and a sense of harmony. Infuse colors and imagery that evoke the energy of the equinox – a mix of warm autumn hues with deep blues and purples. Include subtle hints of stars, constellations, and celestial light to enhance the mystical atmosphere.
