could be my monitor and time of day (I have a bit of a glare behind me from the morning sun) - but they appear over saturated and dark shadows really dark. I don't feel the selective colouring in 2 adds to your composition, admitting I tend to find that technique (like misty waterfalls shot with an ND filter) past its prime in most images, however the ones I have seen that utilize it best seem to delineate their target in a more precise way. Example - ONE apple in a barrel of apples.
I like the 3rd one best but would tone it done a bit to achieve a slightly more realistic image. Otherwise, I see many beautiful shots from you posted here, you certainly have a great landscape location library.
