Design an outdoor garden in Tropical Japandi style, creating a serene green space within the open-air environment, enhanced by a small waterfall and fish pond. The garden is located in an open area, surrounded by minimalistic fencing made of natural wood and smooth concrete, providing a sense of privacy while maintaining an open and airy feel. At the heart of the garden, a small waterfall gently cascades into a fish pond below. The waterfall is designed with natural stones, blending seamlessly with the garden's aesthetic, and creating the soothing sound of flowing water. The pond, filled with clear water, is home to a few colorful koi or other tropical fish, adding life and movement to the space. The pond is bordered by smooth pebbles and small, carefully placed tropical plants such as ferns and decorative grasses, creating a natural transition between the water and the surrounding greenery. The garden features a simple arrangement of plants, including small palms and neatly trimmed shrubs, planted in beds of natural soil or pebbles. A small wooden deck or stone path leads through the garden, offering a tranquil spot to walk or sit and enjoy the surroundings. The open-air setting allows natural sunlight to bathe the garden throughout the day, casting gentle shadows and highlighting the textures of the plants and stones. The soft ripples of the water and the gentle movement of the fish create a calming atmosphere, perfect for relaxation and reflection. The overall design is clean and uncluttered, with a focus on natural textures and materials, ensuring that the air terjun kecil dan kolam ikan become the focal point of the outdoor space. The color palette remains neutral, with shades of beige, light wood, and subtle green, creating a serene and harmonious environment that perfectly embodies the Tropical Japandi style
