Imagine an enigmatic and sophisticated nail design that features a deep black base emulating the elegance of a starless night sky. Incorporate subtle metallic accents that catch light in specks of silver or gold, reminiscent of distant stars scattered across the darkness of a cosmic expanse. Consider adding delicate, thin, and intricate line work for extra dimension or a touch of geometric patterns that hints at an avant-garde aesthetic. To complete this dramatic look, play with textures by integrating gloss and matte finishes, adding depth and contrast to the overall design.
