Sharp capture...I love the details on the wings! Stuart is right, a little CCW rotation is needed if you look at just the feet. The tall figure of the Heron can mislead one in the angle.
With that light it has a wonderful sculpted look. Terrific detail and exposure is spot on. Agree about rotation, and feel a little looser crop all around would be nice if you have it.
Good IQ on the heron itself. I see something was modified behind the subject...I can see the post-processing along that edge, especially the lower right corner. I also agree with some CCW rotation.
