Awesome image. Check out the perfect pose (and HA)! Great BG, and adequate perch. I would either clone out the thin extended part at bottom left of perch, or crop just enough to hide it. The repost is oversharpened, but Ram had the right idea to apply NR to the BG. As posted the image could use about 1/3 less room above. Personal preference.
Niranjan...keep 'em coming. Other than the noise in the BG, everything is very good. I agree with Daniel that you can crop a little from the top..but not a lot.
The BG noise has been mentioned, which can be easily fixed, but other than that a fine image. Great IQ, the light, BG, pose and the prey make this a wonderful image.
