Nice image Yogesh! I like the pose, perch and BG. I also see a crop with some off the left. I would also clone out the OOF bug(?) to the right of the bird under the perch.
Lovely pose, angle, perch, light and bird! BG looks natural to me, but I can see where someone might think there could be cloning. I would like to see a little off of the left, but I can see you probably left it there so that you could show the entire perch. However, the perch is almost touching the left side so I dont' think it would hurt to crop.
thank you all for comments and suggestions. Actually as observed by Marina: 1. I have kept the crop for entire perch 2. there are no cloning artifacts. all those are natural BG patches.
May be i can try again on cropping.
