Cool shot, Jason. I've been having fun with the Tuis in the Taiwanese Cherries recently - waiting patiently for my Kowhai to come into bloom to get them in a native tree. You've capture the iridescence well. I would be inclined to crop some from the top. Only real niggles are the flower parts intersecting with the breast, beak and back.
I agree with you there, its not the ideal tui shot and hope to get better as the natives come into bloom, my Kowhais at home have just started flowering, so hopefully they will visit my trees soon.
A lovely bird I am unfamiliar with. Great job getting the iridescence and the image is sharp,. The flower perch is nice. The flowers intersecting with the bird are not ideal, but acceptable IMO. Looking forward to seeing more of your posts.
I think that with a Horizontal compo you would've gotten more room, or maybe is the pose that is not the ideal as the bird doesn't look "confotable":) Still, very nice species and I can't wait to see more! Congratulations as color, BG and sharpness are great!
