Lovely portrait, Brad. If you're comfortable with it, darkening down some of the white on the upper part of the bill may be an option. Great colours and plumage detail with a very complementary BG.
I like the sharpness, head angle and soft light. I might lower the color temperature a few degrees and wish there were no dark band behind the head. Have you tried a crop off the bottom that would remove the back? Keep them coming!
