A painting of a river surrounded by trees with orange leaves

A vibrant and colorful depiction of the changing seasons, with a focus on the beauty of autumn. The image should show a landscape filled with rich, warm colors, such as reds, oranges, and yellows, as leaves turn and fall from trees. The scene should also include elements such as rolling hills, winding rivers, and towering mountains, all bathed in the golden light of the setting sun. The overall mood of the image should be one of serenity and beauty, reflecting the natural cycle of life and death apparent during the autumn months.
