Hi Mario,
that is a really beautiful scene. This looks really like spring with all the flowering bushes in the foreground. And I love how the light trees stand out against the background.
In my opinion, your image could benefit from a different crop. The lower edge of the image distracts my eye a bit from the beautiful scene.
I took the liberty and downloaded your image and trying different things. Here is my result:
I cropped a bit from the bottom edge to get rid of the dark parts below the bushes.
You had some space in your histogram, so I brightened the image and added a little bit of contrast.
I brightened up the dark patch at the upper edge of the image with a Brush Mask
I adjusted the green HSL values in the Color Mixer (hue: -20, saturation: -28, luminance: -16).
With steps 3 and 4 I tried to make the green dark area at the top of the image a little less prominent.
I added some saturation in the Color Mixer (yellow: +4, oranges: +14) to let the nice flowering bushes pop a little bit more
Of course, this is just a suggestion. Your picture is also great the way it is. I could spend hours shooting scenes like that.
A beautiful scene. I agree with Tom N. about increasing the brightness, but just a tad and only the lights (not a global adjustment). That would bring out the moundi-ness of those lower bushes. The one thing that caught my eye was those strong greens of the pine trees in the upper background. They felt a bit out of place in the overall palette of subdued warm color. I was thinking that reducing the saturation (or adjusting it) and brightness of those greens would make them less prominent. I think it would also increase the sense of depth that you mentioned you liked. Here’s my idea:
