A tranquil river winding through a rocky canyon. The river is a deep teal-blue, reflecting the muted light. The rocky walls of the canyon are a dark gray, contrasted by vibrant orange-red autumnal foliage clinging to the cliffs. The trees line the riverbanks on both sides, filling the image’s vertical space.  The view is from high above, looking directly down at the river, creating a sense of vastness and serenity. The overall color palette is muted with a cool tone, highlighting the rich colors of the autumn leaves. The lighting suggests a soft, overcast day.  The perspective is a bird’s-eye view, emphasizing the river’s path and the canyon’s depth. The composition is symmetrical, with the river center and the foliage mirroring each other.
