This is a striking image, largely due your ability to capture bird calling. Exposure and sharpness are spot on. The image, however, looks a wee bit washed out on my monitor. I think by bringing down the dark areas a bit, the bird will pop a bit more.
I like the perch and the open beak. I do agree about the colors looking washed out and I also find the Eagle/perch to be leaning to the right of the frame...I would consider rotating the image ccw to level it.
Awesome shot of an awe-inspiring bird. Love the perch and the open bill. Agree about it seeming a bit washed-out - just needs some contrast enhancement, maybe with a bit of USM set for high radius/low amount.
On my monitor, the sky in the upper part of the frame has a pinkish tint, probably due to the wispy clouds.
