Gerrie,
This is a beautiful specimen.
The image is exposed very well, sharp and the background is beautiful as well.
I like the composition but feel that just a little more room around the subject would make this image even stronger.
I also notice a sharpening halo around your subject. Sometime Smart Sharpen will help to reduce the Halo, otherwise in a background layer, magic wand the background and add somewhere between .3 and .6 Gaussian Blur. Then adjust opacity to taste.
I like the pose and the head turn. I think that you did an excellent job of getting the details in the dark areas in some fairly bright light. Sometimes the Shadows/highlights command can also induce a halo. I try to keep it under 10 percent.
one of the best drongo shots I've seen Gerrie. James may have point on a tad more space and ditto the slight halo. overall superbly exposed and composed!
Super detail on the black feathers, but your PP on the perch lets you down, I think.
It cant be sharp on the feet and the perch he is standing on blured?
The stump also varies from detail to blur in a few areas? (Or am I seeing things?)
I like the sharpness, exposure control, BG and eye contact. I would give it a bit more room at the left and might have stopped down more in order to have the perch in focus entirely. Sharpening halo has been mentioned.
