Super detail, and I like the complimentary color of the BG. I would personally put the bird higher in the frame, and I do agree about lightening the iris a bit.
A very nice portrait, I like the soft light, colors, sharpness and HA.
I prefer the balance of the Repost, but I think that I would place him a bit more to the right.
Thanks for the comments. I normally prefer to get the things right in the field. However, in this case, I felt the crop was needed. Your suggestions are highly appreciated.
