A very cool action shot!
I think the pose is superb and very interesting, you got a good eye contact and an okay wing position. I also like the little jump with both feet in the air and the movement of the bird shown in the small motion blur.
The whites looks well controlled but I think the blacks looks a little blocked. Might be tempted to lift the shadows by a small bit. A lower shooting angle might have taken this to the next level. Also I suspect that you chose the square crop because of some distracting elements to the left. If not I would like some more room there.

Thanks for the comments everyone. I will be posting some thoughts on the Z6 soon. Intriguing, but still some room for improvement.
Ivan: Yes, there was another bird to the left. I could remove it of course, but felt the pose worked OK with the crop as presented. Agree about the blacks. I will bring them up a bit. They are technically not blocked, but still could use some love.
I was as low as I could be shooting wise because of a fence at that site.
Lol, at the title and pose. I agree about the blacks, and speaking of, you could add a small catchlight on the dark eye in post if you wish. Nice whites and details. I can almost hear this fella from here!
