My take on the image is that the background is as important to this shot as the bird itself. In Scot's crop the background is lost and it appears to me only as a blurry image of a bird where my eye struggles to resolve the image.
Leaving the angular background I feel gives the photo and the bird a sense of motion and an other worldly look.
I think any of the shots would work depending on where and on what color background it were matted with. But I personally like #2. Like Bahadir it reminds me of Phoenix rising from the ashes.
