Snoppy, viewing all your shots on this expedition, which I enjoyed a lot, I noticed one constant, and that is the diffused, overcast grey sky which kills colors, contrast and the shadows that contribute to apparent sharpness. Diffused light is tough to work with, I get a lot of it here, however Light Room has a few tools that help, such as clarity, vibrance, saturation, contrast and temperature. I often just hit Auto Tone to give me a starting point. I also urge you to adopt LR, might both give you new insight into your images and a new lease on life.
...I might also add that you might like to put your monitor under scrutiny, as it may be telling you lies....
