A close up of a bunch of different types of icons

I need to design a simple 2D official account icon that contains river elements. Here are my requirements for icons: Design style: Please ensure that the icon is simple, modern, and suitable for official accounts. Element: The icon must contain a river element to highlight the theme of the official account. Color: Use mild and non-harsh colors, preferably colors that echo the natural environment. Shape: The shape of the icon should be clear and easily recognizable, not too complicated. Size: Icons should be moderately sized and able to display clearly on screens of various sizes. --auto
