Plenty of detail in the bird's wings and consistent overall sharpness without being super sharp. I think there is a bit too much space around the bird for an ideal dt. I'm keeping the fullsize then cropping it to my dt (1680x1050) and at that ratio the bird is a nice size for a restful dt, big enough to be interesting, small enough proportional to the screen to give a sense of space and flying. It ain't easy catching a bird on the wing, nice job.
Think about the photo before and after, never during. The secret is to take your time. You mustn't go too fast. The subject must forget about you. Then, however, you must be very quick.
