The navy blue bodice contrasts with sea-green accents on the collar, cuffs, and brooch, while translucent accents and a glossy finish mimic the mineral sheen of the ocean. The base is understated to keep the focus on the figure's elegant silhouette, with careful balance to communicate motion. The sculpting emphasizes slender limbs, a poised neck, and a serene facial expression that reflects Neptune's calm, perceptive nature. Overall, the piece embodies the refined Bishoujo aesthetic and offers fans a museum-grade display option.
