Autumn on the Alouette

Many levels here - not only the surface of the water, of the rock, and of the leaves, but the intersection of that surface, and some things completely submerged, yet almost visible. Plus the action of sinking leaves and the colliding ripples, as well as the flowing water. The dimension of change - the flowing water again, the erosion it carries out (wearing down of banks, of rocks), and the rotting of leaves - as well as the fact that changing season has sent the leaves into the water in the first place.
