Beautiful bird, and it looks like the D70 is delivering for you! Both the light and head angles could be better though IMO. Would you have been able to move over to your right without spooking the subject or introducing unwanted elements in the frame?
Rakesh, this is a beautiful image. Daniel brings up a good suggestion with regards to moving to the right. If you couldn't move to the right, I might consider cropping a bit closer from the right and adding a little canvas on the left. Very nice shot.
