He was a little kid in your pic, OP. Now that he is a little older - a "tween", he's lost that prettiness. His face is thinner and more angular. He's looking more like Rande and less like Cindy. Plus, they've cut off all his hair. His sister is now the "prettiest" one.
That being said, he will still be a very good-looking teen and adult man. I'm sure he could pursue a modeling career like his sister if he wanted to do so.
Unless the genes skip a generation, he'll be just fine as he grows up. Glad to hear they cut that hair.
