Head looks totally parallel so that's good. Light looks soft which is good but I might try a tad more contrast to see how that looks to you. I would crop some down from the top and perhaps the bottom. Pano might look good here too.
Thanks Robert, I'm glad you think the head turn is OK. At a higher magnification it looks as though it is slightly tilted away, but it is barely noticeable.
Your welcome Aidan. Posting from a different computer and the contrast looks good here. On well - that's why I said see how it looks to you.
On the head turn, I notice that you are a bit behind the bird. You can tell that from the legs. If possible, try to get a bit in front of them and the head turn issue become less problematic though you still have to watch for it.
