I really like this shot, it is creative and interesting. What would have improved it for me is if you captured a side profile of the bird so it was more recognisable.
Beautiful image. Wish the bird was more dominant part of it though. Yes, I see him, but he's almost like a secondary character next to the brilliant cloud or the huge pole. Well, shot, well cropped and composed. Good luck in the Challenge!
I like the lighitng of this photo quite a bit. There is a fair bit of noise which is slightly distracting. Interesting colors, love the silhouette. Good composition.
