Beautiful. I have never seen a picture of the juvie one before let alone this pose so thank you for sharing!
Now to nitpick, I think the image could benefit a slight CW rotation and a tighter crop from the right. It's a little awkward for not having a negative space on the left but on the right. I think the bird is properly exposed. You might still be able to brighten up the whites just a little bit more without blowing them out. The details on the neck is stunning.
Hello Stuart. Beautiful bird in an unusual pose. Lovely eye contact. Agree with Adhika about the crop...if it is one. Maybe a bit more room in front and on top if you have it.
I have noticed that you are a man of few words (maybe you find a keyboard awkward) but I was wondering if you could elaborate just a little more on your image/s. You are such an accomplished photographer and I would love to learn a bit more from the image posted. ISO? Handheld? Cropped?
