What a cool bird - is that color real or is that what you changed?
Here I really think the top should be slightly cropped, perhaps to just above the yellow bird. As it is my eye gets drawn up the path to the end of the line of birds where I realize there was nothing to see up there. By cropping you remove the "nothing" at the end of the path which does a small part in keeping the focus on Tom. It also allows the imagination to believe the birds go on forever ;-)
