Can I make this look better?

I took the following photograph yesterday afternoon:
I have done no post processing and I'm generally unhappy with the way it looks. It doesn't seem to have any real impact. The scene looked much better in real life. My main questions is:
Can post processing save the image?
If so, what do people recommend to improve it? If not, what would I need to do differently at the time I took the photograph to improve it?
