This is meant to be constructive criticism, and I hope you take it as such:
Personally I'm not a fan of heavy processing, but that's not where the criticism would take aim. A bunch of the shots themselves I like, just not really the processing... not my cup of tea. Though one I do like a lot is the mountain side. Processing worked very well on that one. Some of the sky shots have blown highlights and gradations, which (for me anyway) is a distraction from the actual scene.
What I think would improve these for the most part is the use of graduated filters. The foregrounds in most of these are very underexposed, but at a level that isn't close enough to what would make a good horizon silhouette. At least with a filter, you can expose the sky properly while maintaining that effect.
