to me the greens look a little too dark and maybe the darkest of the blue in the sky, but it depends on the effect you're after, this is just a suggestion for an experiment to try but next time you're out shooting why not try taking the shot in b&w as well as colour using the same settings (obviously) then try to achieve what the camera produced for the b&w in your colour shot and see how that goes, i've been meaning to try this myself but have never remembered to do it when i had the right shot for it
