Excellent work on the exposure. Your subject is a bit tight in the frame for my personal taste and a little more room on the left would give the bird some space to 'look into'. There seems to be an OOF anamoly towards the bottom of the perch on the lower right corner that is a tad bit distracting. These nits are somewhat minor and I do think this is a beautiful shot - the light, color and detail is great here and I would be happy to have such a nice Bald Eagle in my files!
Great pose, but I would move the bird more to the right. The whites in the neck look a bit to me too and the cloning in the perch needs to be cleaner.
Nice overall work :)
