Create a stunning dip powder nail design that encapsulates the essence of a whimsical sunset on a tropical beach. Imagine the vibrant hues of coral, peach, and soft lavender blended seamlessly on each nail, evoking the tranquil yet colorful transition of day to night. Add a touch of iridescent shimmer to mimic the twinkling starry sky, and accentuate one nail with an artistic palm tree silhouette for a hint of tropical charm. The overall look should feel refreshing and summery, perfect for a serene getaway or an everyday splash of vacation vibes.
