The second drawing on 12x16 watercolor paper early on became rocks in the whitewater of the river rapids. There is a lot of detail that I think looks good for that whitewater. I've used collage, acrylic paint and black, white and gold inks. It was amazing to put it next to the first large one to see how different they were even though rather similar. A lot of water themes have arisen in these drawings. Remember you can see this larger if you click on it. A right click might give you other options and the ability to see it even larger.
