First, I would kill the second (bottom) image. The scene did not actually look like that, and it definitely is not a pleasing image. However the scene was metered - either by you or the camera, the shadow areas were used as the target, so everything got shifted brighter than it should have. If in doubt, let the subject fall into shadow rather than lose it in the highlights. (That's applicable to just about every subject matter.)
The first image is better and does follow that guideline I just mentioned. The right half is nice with the light source, clouds and distinct trees coming together successfully. But the left half is missing something. There is too much shadow there, with the tree line creating a black mass. I'm wondering how it would have looked if you had recomposed it so the right half moved to the left side, or even if you'd zoomed in a bit.
