I recently purchased a Canon 700D to get into photography. I'm trying to improve, but my photos seem 'boring'. Let me give some examples:

I took these today. The scenery looks breath-taking when viewing it from the highway, but I utterly fail to convey that in my pictures. Any tips for a beginner? Anything you see that is obviously wrong in these photos?
