All are quite interesting shots of birds, Abhi. My personal suggestion with these kind of shots are:
1. Watch out for those uncooperative twigs and branches.

If you can clone them out, the better.
2. Watch how you position your camera and notice if the background is supporting your main subject or not.
3. Wait for that special moment where they are doing something unique (or the pose is really nice) to make the shot more interesting.
It's really hard to shoot birds. I have to commend you for taking the effort practicing it and came out with some nice shots as these. Hope you will take some more shots and show it to us in the future.
