|I think you are going to get this quite a bit in the comments, so I just point out the bad in a quick list. Too much staturation, centered horizon, too much contrast, and the staturation doesn't not seem to be even across the frame (blue on one side green on the other).
Now I will expound on the good points:
Very nice dynamic clouds going on here, they fill the top of the frame nicely.
This looks liek a great study on color, just tone it down a bit and it would really sing.
I like the lines and patterns with the mountains, farmland, and forests. It gives a good texture. The rolling hills and distance clouds also give good depth to the photo.
I'm curious what the original looked like. Still not a bad landscape just a bit over processed.
