Hey Antonio, upon first glance it worked fine for me.
Some nitpicking if you want it:
The foreground tree's shadow is roughly the same hue as the sunlit grass, you may want to shift it *slightly* toward blue-green. Also, in direct sunlight, tree shadows tend be more defined, with breaks where the sunlight is filtering through. The current shadow looks more appropriate for an overcast sky.
You may want to revisit the integration of those two foreground rocks.
The hue in some of the background black levels is a bit too differentiated for my taste, namely the rock face on the right, which could benefit from a slight shift toward blue.
Hope that helps. Like I said, it fooled me at first, but I think the tree shadow is your biggest obstacle. Good luck!
