What a lovely pose and bird. I agree about wishing for just a little more light on the bird's face. The neck feathers nearly blend into the background.
So much interest here. I've never seen this bird before. I think that the bird needs to be a bit brighter and there are sharpening issues with the tail, (they look jagged) but I have no idea how to sharpen something like that...hopefully someone else will.
Nice looking back pose and nice colours in the bird, Satish.
If it were mine, I would select the bird and would use highlights/shadow tool or other means to make the bird a bit brighter.
Here it is with some shadow/highlights adjustment on the shadows only I think at 15 points. I think when sharpening this image, I would not sharpen the tail.
