Nice simple portrait. Perfect exposure, and lots of beautiful details. I like the vertical crop (original vertical?). Perhaps a bit more room above would be good, but I still like it as is.
Agree with the comments above; superb exposure and details. I'm amazed at such an awesome frame filling shot with a 70-200mm.
Lovely bg, and another vote for some more room above.
I like the perch too, but if anything, I wish it didn't block the tail.
Loved the pose, exposure, composition, head position, perch and that BG is gorgeous. This is a terrific shot. Only thing is that the bird looks a tad oversharpened to me.
