Ooh, I love that second one! I'd agree with Dune, you've gotten much better! Love those rocky hills up top, great texture and coloring, it looks very realistic. The way the trees fall on the folds of the mountains is great also, very natural, as well as the blend of species.
The foreground is awesome as well, great mix of vegetation, though the rocks poking out of the water could maybe use a touch more detail? Mostly just that one on the left, I'd perhaps replace it with an object. I kind of like the clouds as is, but there's always room for experimentation.
My only real crit is that the people on the right are too close to the edge of the image for my taste. I'd either leave them out or expand the camera angle a bit to pad the edge a little. Otherwise it looks like they were accidentally in your nice landscape photo
