Here is a quick edit. Keep in mind, I would prefer to work with a larger photo, I have been using the NX2 software for all of two days and I believe you are a better photographer than I.
I set a White Point, adjusted the Brightness using Levels and Curves, and ended up bumping the green in the foliage using Color Control Point. I think this program, Nikon NX2 is easier to use than photoshop!
