Wow this is a gorgeous shot. I love the perspective of this image, looking down on the bird in flight isn't something I usually see. It feels like I'm actually up in the air flying with the bird. Plus its crystal clear and sharp, I love the details on the vulture. The DOF looks great as well, I really like how it rendered the (back)ground. Wonderful job on this!
This is absolutely breathtaking. Not only did you manage to capture the bird in flight with impeccable detail and clarity, but it's also a position in which birds are really difficult to capture on film! Perfect composition.
