I don't know if 'looking up' necessarily meets the challenge of shooting something from the perspective of the ground up. Setting that aside, the only thing to look at in the photo is the bird and the bird is out of focus. MAybe you were going for a soft look. I submit soft focus shots purposely and routinely get reamed for doing so, so I'm not holding it against you persay. However when there is simply nothing else in the shot and you can't make out any detail on the one thing that is in the shot you don't really end up with an interesting photograph. Good effort.
