I agree with Rajan. A higher shutter speed would have been better in freezing the motion. If you are in doubt about sharpness, then look at the catchlight in the eye and from that you can know that the image is not sharp. The catchlight will come a bit elliptical. The sharpening has introduced artifacts on the body feathers and that is giving a false impression about sharpness.

Since this is surely a cropped image, even though it is not mentioned, complete tail in the image would have been better. Thanks for sharing.
