After I completely muddied up the left side shrubbery I decided to try a new fern technique. I think it's kind of interesting, but not the right style.
With this second one I did a much better job with the foliage on the left, but there are still a lot of other issues. The first thing that jumps out at me is how the waterfall isn't perfect horizontal across the top and is defying gravity. There are also some gravity-defying rocks floating near the middle. Oh dear.
Just look at the flowers.
