Sharp, well exposed, soft light, interesting pose. Smooth background.
In a perfect world, wish the light had been a bit more over your shoulder to light the face a bit more evenly, but I think you could bring it up a bit.
Sharpness, exposure, background and pose are really great. And I like the side lighting as there is enough visible detail in the shadowed face. The poop in front of the bird and the little stringy thing in the lower left corner could go but I am not hung up on it. Agree on more room at the top. Congrats.
I like the pose, rocky perch, and green BG. Sharpness is good. I like the idea of cleaning up the perch a little, and I agree with Randy about the lighting of the face.
