Black Ribbons in the Sky

Yup, I realize my barn has a serious slope. I wanted to paint quickly and not get caught up in the details. I was afraid if I started fiddling with the lines I'd lose the looseness of the painting and I liked that. This was across the street from the cows (from my last post). While I was painting the cows, I looked over at one point and it looked like a black, lacey quilt blowing over the field, there were so many birds, a minute later they were all gone...
