interesting, but purple hue of the sky gives it a look that i'm not sure is best for this image. perhaps a darker/rustier looking hue/saturation modification for the truck would work wonders.
This image has nice pleasing dimensions demarcated by the horizon. Love the colors in the sky and I feel you did a good job with the post processing. Technically sound photograph. If I were to nitpick, there is just a slight blooming at the tree edges against the sky, which is subtle enough not to detract from the beauty of this image.
Good work - love the sense of location, so important to these shots. I think you could have darkened the foreground a little, and added impact thereby - it would have brought out the yellow tones in the grasses, and complemented the sky quite efffectively.
To me the most interesting part is the truck, and it's also IMHO what made this fit with 'broken'. I would have concentrated more on the truck itself but a good idea never the less.
I bet this one will do well. Perhaps if you'd have moved a touch left, to get teh barn off center - sort of have the truck pointing at the barn to lead my eye through the picture.
