i went for the painting look as well.....
the first thing i wanted to do was correct the color of the foliage....isolated it and corrected with a locked layer of levels....blue slider pulled right....same adjustment on the mountain, sky, and water.....but less so.....evened out the scene's color with a layer of orange turned way down.....painted with underpainting filter.....selectively lightened and darkened areas of the scene to taste.......thought a little sunshine would look nice, so i panted in a diffused yellow in the center of the trees.....vignette and that's it.....
peeper
