Looking at this the second time I am diggin it. The sun may have burned out that bit a little too much but overall I enjoy the processing. White-space at the bottom may be a bit much but overall this is nice. I will give it a slight bump.
Too bad you missed the Contre Jour challenge; this would be well suited for that. I kinda like the lens flare you got going on here too, as well as the obliteration of everything but the barn. Interestingly, it seems almost in direct contrast to the barn's place in the world, wherein small farms and the associated are being obliterated by the changing times and giant agri-business.
OK, I'm going through the Free Study submissions, purposefully finding those images I think are shot with a less conventional eye - this is one of those images! Thanks for offering something that isn't just DPC friendly eye-candy (though of course there's nothing wrong with eye-candy). I'll be picking one of these images for the Mu (most underrated) award:
Positives: Excellent contre-jour composition, I really like the lens flare too. The negative space is (mostly) marvellous and the building has plenty of intrinsic interest. I the slight violet touches it has introduced.
Critical stuff: I wish you had cloned out the shadowed areas at the bottom of the image and kept the negative space unsullied.
Overall: An effective image that is more than the sum of its parts.
