Imagine a set of BiAB (Builder-in-a-Bottle) nails inspired by a tranquil waterfall scene. These nails feature a gradient base transitioning from soft azure to clear, representing cascading water. Softly overlapping waves are painted in a shimmering silver at the tips to mimic flowing water. Enhance the serenity of the design by incorporating tiny, hand-drawn water lilies and dragonflies. Finally, add a touch of iridescent glitter to evoke the sparkle of sunlight dancing on the water's surface.
