This is one I am not familiar with, so always fun to see a new one!
Good look at the head, and I like the angle of the bird in the frame. Exposure is good. Generally full up or full down wing positions are more dynamic. This flatter pose is helped here by the flared up primaries.
Interesting green cast under the near wing. I assume it is a reflection?
The cropping is much too tight for my taste, exp. to the right, but really needs room on both sides and below. Always helps to have room to fly into, and to not get the bird too close to the frame edge.
Agree with Randy's comments on the crop and wing positions. Light conditions seems pretty harsh and contrasty. Sharpness good and nice underwing details.
