Hi Satish... This looks pretty good to me.. Nice clean (in every sense...) image. I do see a hint of noise in the darker under tail, but its pretty trivial..
Delightful bird! First time I've seen one, and it's a stunner. Love the head angle and eye contact....one idea would be to play up the empty space on the right hand side by placing the bird a bit further to the left...Possibly consider cropping some off the top too if you were to try that.
