The bird looks great; nice and sharp with great light and good eye contact. The green BG is pretty. However I find the parts of the perch behind the bird to be significantly distracting. Also I'd like to see the bird placed in the right of the frame. I'll try a repost; check back a little later.
Kiran I am not familiar with this species but I think that the colors are a bit flat. The light is strong but I like the pose of the bird and the neat eye contact. From a compositional point of view I agree with your self critic... more room at the left is necessary and another round of noise reduction to the BG would be great :-)
Very nice image. Agree with Doug on the composition. Maybe his rework is too much modification on this image. I would leave the bg branch as is. A tad of sharpening would be useful.
