That's incredible! It's funny that you were going for the crisp shot (which would have been cool) but this was amazing! I think the most interesting part is that even though the wings are blurred, it's like watching a GIF. You can imagine the movement. And the head is fairly still, so it's a neat contrast/complement.
Thankyou. Without the head relatively still, it would not have worked quite so well. Even if it was intentional, you might have to be lucky to get that.
