Nice pano and sky, this is a healthy looking guy.
I would suggest trying to recover some detail in the blacks and to try to remove the yellowish/greenish cast in the right wing and breast. I also might be tempted to sharpen the eye a little and make the catch light a little bigger. Other than that this is a great image.
I agree with JC about the blacks. The sidelight here created a superb patter of details in the underwing feathers that I like a lot. The shooting angle is a bit steped
