I would like to see a variety of rocks textures to draw from too. Rocks you would find on the river bottom. Ex: Cambrian sandstone rock found in the Wisconsin River dates back to over 500 million years to when Wisconsin was still under the sea.
I also meant to say that I enjoy seeing a bottom feeder(crayfish) and there are many varieties of grubs/larvae to consider that live in wisconsin riverbeds that could occupy the bottom layer of the image much like the front of the biosphere bus
