The sky is really blown out here and the barn feels a little out of focus. If it was possible to get inside, I'll bet some of the old framing beams might have had some good angles to try to shoot and may have not been so bright for you.
This is just a simple suggestion, please don't think I'm criticizing your photographer ability here. -BB
Nice composition, but the color seems way off. The barn looks purple on my screen. Perhaps you adjusted your white balance incorrectly when taking the pic?
Sky seems a little to "hot". Also ground is very distracting. Getting closer, and not cutting off the very back corner of the building would have helped
