The soft light is great and the pose is classic GBH.
The crop and framing are a problem for me. I would really like to see this in a classic rectangle crop the square does nothing for it except make me wish there was more room in front of the bill and less empty space on top.
A 3 second curves adjustment to open up the face would make the image even more attractive.
Love the lighting - and quite a catch. Tried to lighten the shadows a little and added some canvas in front of the bird, cropped from the top - this might have centered the bird too much though.
