For a first shot, it's pretty good. I agree with a couple of the earlier comments that cropping it so that the birds is not centered in the image. Since it is looking to the left, I would crop it so that there is more space on the left to give room to "look into".
It looks a little soft to me as well, was this hand-held or on a tripod? Pierro is correct with the VR, if on a tripod, turn the VR off, shutter 1/500 or higher, turn it off. I would have bumped the iso up to 400, which would have let you use a higher shutter speed, helping you to get a sharper image.
