A modern outdoor swimming pool with a waterfall feature at night. the pool is rectangular in shape and has a clear blue-green water surface. The water cascades down from the top of the pool into the pool below, creating a serene and tranquil atmosphere. The pool is surrounded by a white tiled wall and a black pebble wall on the left side, adding a touch of contrast to the modern design. on the right side of the image, there are tall, green plants adding a pop of color to the otherwise monochromatic scene. the lighting is soft and warm, casting a gentle glow on the water and creating a sense of tranquility. the floor is made of dark grey tiles, and the overall aesthetic is minimalistic and contemporary.
