And what a stare!!! Kiran, I like the comp, well exposed, and really sharp. Super BG too. If I had to change anything, I would maybe darken the BG very slightly. Still, congrats on a fine image.
I like the stare, angle, soft light, composition and BG. The image looks a bit oversharpened which could be partially due to the high ISO. I would work on the eyes and remove the horizontal bright lines in the pupils.
Good symmetry with the stare. I like the complementary colours and tones in the BG and plumage that highlight the eyes. You've done well with the DOF to keep everything sharp. I agree with Axel's suggestion regarding a touch of selective eye work. Well done.
Love the stare! Great close up. I won't comment on the sharpening, as I am really messing up my pictures on the sharpening front. Personally, I would leave the eyes as they are.
Well done from all aspects. The stare is quite mesmerizing...such glowing yellows (were the yellows "boosted" in PS?) Getting rid of the horizontal lines in the eyes is subjective, but I would do it. P.S. I don't consider 1/640s at ISO 800 very low light ;-)
Sorry Daniel: forgot to mention, I did brighten up the eye by 9 in PS to the right. they have great glowing yellow eyes, may be beause that hunt in very low light,
