Hi Rohan Good looking bird, sharp and well exposed
Would like seeing you moved just a bit to keep the perch from intersecting the head and a slight twist of the head toward the camera. Bg is manageable wold tone down the brighter white branch? LR and might get rid of the stick by the tail Also can lighten the face a bit which might have been different with the better head angle !!! Excellent !!!
All good points by AL, and I would add that I would have preferred had you pointed your lens down a bit more (to place the bird higher in the frame). I like the rich dark blues on this guy's plumage!
If it turned the head a little more toward you, you would also have had the bill in the plane of focus. Lovely colors and the guys already gave some good tips mate. You should always use the histogram and push the graph to the right as far as possible without clipping the highlights. If you don't know what I am talking about, see this link.
