Looks awesome Doug... still amazed at your handheld technique with the 600, and the incredible results. Great detail! Do you deal with any noise on the sky in an image like this, or is the MIII clean at iso800?
What a lovely looking raptor. You did great with that light, sharpness and compo.
The only thing that bothers me is the dark halo on the base of the wing right behind the nape. Overall a great image.
Nice capture of this lovely bird, good eye contact and composition. The dark halo mentioned by Juan Carlos is a bit of a distraction but an easy fix. Well done.
