That's one beautiful bird. The head turn and clear view of the eye are great . Also I like the pleasing background, and exposure looks good. To my eye, I would wish for a little more Dof. I would like to see those beautiful yellow feathers sharp as well as that stunning bill.
Great looking bird and background. Agree that some more DOF would help. I haven't seen one of these in real life and it could be me, but the blacks and top of beak seem to have a slight blue cast. Thanks for sharing!
