Create a mood board with the concept of a tranquil Zen garden. It should include intricately pruned bonsai trees among the meticulously raked sand that represents rippling water. There is a serene koi pond in the middle, dotted with colorful koi fishes, possibly of orange, white, and red pigments. Stone statues of Buddha and stone lanterns are meticulously arranged, adding to the overall calm atmosphere. Gentle bamboo shoots swaying in the wind, creating peaceful soothing sounds. The scene is embraced by a backdrop of lush greenery. The palette for this board includes tones of green, tan, orange, and red to emphasize tranquility and peace.
