There is definite potential here. It does look like the colour is a little off; did you adjust your levels at all? There looks too be too much green and purple.
I believe you've chosen a good subject however I get the feeling that the colour was adjusted here. The sky seems to be a weird lavender and the barn seems to be pink. Also, even though it appears to comply with the rule of thirds there is too much sky and possibly too much field in the foreground. It may work better as a panorama.
This is a place with potential. I think that you have made the most of your conditions there, but try returning when there is a dark and moody sky, just after a storm with clouds and such. This will add much more impact. In this shot, the sky is bland and boring and it takes up literally 1/4 of the photo, so in that regards, 1/4 of the photo is losing its interest due to the uneventfulness of the sky. Sorry to roast, but my other criticism is that the barns have been overly dodged. But don't be disheartened! Get back out there, brave the conditions, and shoot again!
