Greetings from the Critique Club.
I think this image benefits from some fine colour accents; the blue sky, the green and orange around the face too. I think you have the highlights at the right level too, bright but still with plenty of dynamic range.
Sharpness is a slight problem, the feet are perfect but unfortunately they aren't the most interesting part of the image. I'm surprised to see this as a 1/1600s capture, I'd have expected to see 'frozen' wings at that shutter speed, perhaps the unsharpness is all focus related. You've filled the frame admirably for a 105mm bird shot but I think the centre placement isn't the boldest or most interesting.
Overall this is a good shot, it scored well in the context of a Free Study, especially one that came on the back of a bird challenge.
