That eye is great. Great pose and eye contact. I would compose the shot with the bird a little lower in the image placing the beak on the top thirds line.
The eye is absolutely stunning, I would have cropped a little more at the bottom to eliminate a bit the effect of the "contre plongée" (I don't know this word in english, sorry).
Vinay, please specify the equipment details and all the techs( aperture, shutter speed and iso). Its something all of us do at BPN.
This is one of my favorite birds. The red eye catches attentions. Head seems a tad less sharp than the back. Might be a focus point issue. Dont know what the aperture was.
Loved the pose and other than whats suggested above, I dont have anything to add. Keep 'em coming Vinay.
