Nice capture Satish, bird very crisp. I notice on my Mac some lines in BG going from bill down and up, in different shades of green. I have noticed the same in some of my images while processing, I can only attribute it to blurring on a big crop. Can anyone shed some light on this?
Excellent pose datails and eye contact, Satish.
The lower part of the background is a little too bright on my computer, you might want to tone it down.
Nice details on the subject, good colours and nice blacks. I like the diagonal perch but wish there was less shadow on it. I like most of the BG, the leaf in LRC distracts more than adds in this case (IMO). You've chosen a well balanced vertical composition. Tail and rump seem a bit sharper than the face, perhaps that is where critical focus was at?
The lines Andre mentions look like posterization that can be caused by compression due to resizing for web.
