The dark spot on the top right almost looks like your lens was obstructed by possible a camera strap or finger in the way. Your subject is a bit too far away to draw attention to it as it should be, causing the lines to overwhem the photo. Maybe a closer different angle.
your scene is very interesting, though probably more so without the foreground column. more of a zoom on what currently is the focus of the shot and a bit more saturation to accentuate the blue sky and green grass would have made for a very intriguing pic in my opinion
Wow, power lines that work as great leading lines. They add so much depth to the photo, one of the few times where they are actually functional in a photograph. :)
