After looking at your landscape gallery, I’d have to say that you have a decent eye, but you’re having some difficulty with processing.
The vast majority of your photos are way over processed with a few that are catastrophically over-processed while still fewer look about right.
On a scale of 0 to 100, with 0 being straight out of the camera and 100 being your average finished product, I would say you need to cut it back to about a 30.
