Lovely bird.

I agree with Roopak. It looks a bit dark. There is a dark spot at the centre which is bothering. This is despite the composition with the kingfisher at the top left corner and the beak pointing diagonally down and your name at the bottom right with white font. So it would be better to brighten it a bit and pull up the shadows/blacks a bit.
