Bird is obviously concentrating on a catch, so head angle is acceptable IMO.
Your techs seem a bit extreme. You don't need 1/4000 of a second for a static bird and you sure could use the DOF. Lowering the ISO to 400 would have been a good choice and use at least f/5.6
Troy nice shot. I can see why you wanted the 1/4000 of a second on the static bird as it was in prep for the action shot. Could have a little more sharpness to the beak area but you certainly are learning quickly. Keep up the great work.
Troy, I liked the contrast. All good suggestions above. In addition, I'd say including more room in the front and less on the right side would have been better. The crop at the foot bothers the eye. And since the gaze is intense, the viewer focus on that. With that little room in front, the eyes quickly follow the gaze out of the frame. Nicer frame would have been one with more room on left....the bill pointing into the corner and the right edge somewhere near the 'gra' in photography of your signature. My 2 cents.
On second thoughts, may be the right edge can come in even further.
Troy, I wasn't suggesting you crop. Just pointing the camera a bit to your left would have done the trick. But I totally see where you are coming from. I also find it hard to shoot large birds when they get that close. Its easy to do armchair quarterbacking later....but in the field, I always miss simple adjustments.
