Well. A couple of adjustment layers, a couple of minor color changes, and it's a world of difference. To me, at least.
I need to put pink-and-white flowers in the foliage on the left, increase the contrast in the foremost mass of foliage, deform the lower right-hand side of the red rock in the middle to fill in the gap under the pitcher plant, cut an appropriate edge in the soil at the same spot, and then make the big rock in the center lighter.
But it's almost time to play music, and I need to shower, so it ain't getting done today. Getting close, though.
