Nice! I like the sharpness of the weeds with the structure in soft focus in the background, as if it is disappearing (it looks like it's on its last legs from what I can see of it). When you return this month you should capture the same image now that the cycle of nature is about 180 degrees, to see the regrowth.
By juxtaposing the work of nature and man, you comment on the cyclical nature of both. The weeds of October will bloom again in the spring, while the old barn, seen in soft focus, implies that the past is always alive in the minds of men.
