Have you lost your darkest darks? Go back and put them in. Then look at the lights. If they’re not light enough, begin to key them up using a bit thicker paint.
Adjust colors and make them sing. But don't add detail, infer or suggest it. Don’t get stuck in one place, work holistically all over the canvas.
Let the paint be paint – don’t force it to be a tree or a flower. It has beauty in itself.
In the photo you can see I darkened some of the darks, then added more reds and orange and light green to areas. Some cooler greens were added to the river and the foreground.
