Sophisticated and Otherworldly Album Cover for a Classical Crossover Project

Design a sophisticated and otherworldly album cover for a classical crossover project titled "Celestial Reverie." The album's sound merges orchestral strings, airy soprano vocals, and electronic textures to evoke cosmic awe and divine tranquility. Feature the title "Celestial Reverie" prominently across the top, while the artist name "Astralis Ensemble" appears subtly at the bottom. Include a radiant celestial body at the focal point, encircled by flowing nebulae, with streams of shimmering light cutting through a starry expanse. A delicate constellation crown should embellish the celestial body, and abstract floral designs should seamlessly integrate with the cosmic motifs along the edges. The text should use an elegant serif font with intricate flourishes, embodying a timeless and heavenly aesthetic.
