Sabya, this is amazingly sharp, and just love the feather detail. I made a comment on a previous image of yours regarding their beaks. Well, this sure is one mean beak too. I agree, adding to the right will work. Well captured.
Another vote for more room at the top and right and I like Axel´s suggestion about the eye. I would try to tone down the BG just a bit and I love the pose of the vulture :-)
