This could have been a good arrangement of complementary colours if the baby's bath toy had been more of a green colour to contrast with the pink skin tones. And then the photo cropped more tightly to cut out exess background.
Very cute baby, but image has more of a snapshot quality. I don't see any complementary colors. If they are there, it isn't obvious to me. I say again that this is a beautiful baby - those eyes just sparkle.
