Standard settings are maybe a bit strong for this image. The results above came from a brief test using these settings:
Note that I set Tones to Linear and film to something other than None and pushed the Hue slider to the right. You might also try with a lower pre-saturation value. Here, I left it at its default.
Note that I converted your jpeg file to 16 bit tiff before conversion and tweaking. Jpeg is simply too limited for the color corrections I wanted in this case. The image at the right is a tiff copy that I used to change hue and saturation of sky, skin and forest. All changes made are global. Skin tones could further be treated with local corrections.
