That's a nice harrier! I love the wide-open beak. The background colors are nice--the BG sure complements the beautiful yellow eye. I like the position of the subject in the frame--it might also make an interesting vertical. The feathers appear a bit noisy on my monitor.
Nice looking calling pose and I like the BG colors. Not sure why, especially with the camera that you have and the low ISO that you were shooting, but the feathers are pretty noisy. Looks like it might have been under exposed and then brought back. TFS
The repost still has lots of noise on those feathers. On a properly exposed file you should not have to use NR on the subject unless it is either heavily underexposed and brought back in post, heavily cropped, or heavily sharpened on a soft image.
I do love the dynamic pose and you have some nice colours in the BG. I wish the head was angled our way though.
Would you mind posting a resized version of the original unedited frame? That amount of noise means either your original was significantly underexposed or that there's something wrong with your camera.
