I love the emotions in each eyes. Nine is sadness,grief,but if you look closely you can see a spark of happiness.And he will cling to that bit of happiness for his life. Ten's is still sad,but more youthful. He's looking at every little detail while still trying to be happy because that's what Rose would want: Him to be happy. Eleven's is still trying to keep a grip on that happiness but it's getting harder and harder. And no matter how young he looks,he remembers ever gut clenching death.
