This is a wonderful clear and very well positioned subject. The eyes are well lite and have great feeling,with the feathers ruffled it moves away from the formal shots. The back ground is defused well. With a foreground that complements the subject.
I like the muted colours and the fact that one has no idea it is not a wild bird you just happened upon.
The space to the left of the picture is ideal for presentations and give the picture room to breath. Did he just land or is he about to take off?
One can imagine the rabbit is just out of view..
