I like the effort at the phone wires being part of the subject instead of a distraction needing to be cloned out. Nice color on the sky. It may be too busy to have real impact for me, though. A closer crop on the central subject might have done better for me.
I like the silhouettes although it is a bit contrasty, that makes the lines jagged. Not sure if you enhanced the colour of the sky. Not sure if I like it or not.
I really like the way you have composed this shot. The lines have formed a really nice effect to my eye. We often try so hard to get rid of power lines from our shots it is a great take on this challenge to feature them prominently as everyday beauty. The background sky is wonderful and provides the shadow as subject that really makes this shot work for me. The only thing I have as far as critique is the dark spot in the bottom right. It does attract my eye pretty quickly, but it is a minor concern. Great shot. Not sure how well it will do in the scoring, but I really see it and hope others do as well.
I gave this an 8 because although the image is fairly untinteresting, it does focus you to look at how the birds sit on a wire! Which I believe fits the challenge well.
