|Hello from the Critique Club!
First of all, this is an interesting, candid shot. It does however, have a snapshotish quality to it that seems a little bland to me.
This image would benefit from being more sharp, as well as having the colours more vivid. The details of the feathers are lost on the bird, he would be much more interesting if you could see all the little feathers on him. The cage is very distracting, but may have not been an option to remove it. If that's the case it's very unfortunate because it would be a much better image without it.
The photo has a certain charm to it and is amusing. It generates a response from the viewer, so it is a successful shot.
