What a spectacular moment to have captured. Good job. Much to improve however as bird photos are very tough to get right. The white is very over-exposed as all detail is lost. Try to meter on just the white areas and then stop down a little. Also sharpness could be improved as the detail in the feathers has been lost. Stick with it and I'm sure you will be rewarded with a treasure.
I think the image suffers from bad focusing and overexposure. The white feathers don't show any detail. Good effort though. I have'nt taken photos of an eagle or any bird for that matter and I'm sure it's not easy.
You captured the eagle, and the composition of your shot is good. Unfortuantely, the image is overexposed and not quite as sharp as it could be. Probably, you didn't have time to change your settings when this wonderful photo op presented itself. In any case, this would be a difficult shot to expose correctly because of the very strong contrasts involved.
