This is a good capture in many ways but it doesn't really grab me. And that suggests that you were 'close enough'.
If you crop down significantly you can make the eagle more dominant. I'm posting a cropped version.
I also darkened a few spots that seemed pull my eye away from the subject and sharpened the fir branch on the left. You might also try some careful dodging on the bird's head to reduce the effect of the shadow.
