Sad to say I think the image is a result from a recent dpchallenge challenge of minimalizm.... I don't think the composition works for this challenge. Sorry
I like the concept, however, I think that the image would have a stronger effect if the right hand side was cropped right the the corner of the house. Just my opinion...
rule of thrids is obvious here but i think it would have been better represtned if the sky was a little more interesting, maybe a closer shot on the roof would have helped with the sky also
