I love seeing the eagle in snow and in the environment, however, I think the composition would be better with some off of the right and having him look into the left side of the frame. I also wish you were a bit higher when you took this frame, but I understand we have to let nature govern from where we take an image most of the time.
Love the mood in this image. I agree with a bit of tweaking with the composition can improve the image. I wish the head was just a bit more in focus with a bit more of DOF.
