Teenage Andy didn't really resemble kid Andy.
I was surprised to see how they changed his character design. Of course a teenager could look entirely different as a teen as opposed to how they looked as a kid,, while some teens does have the same features as they had as kids. But teenage Andy looked entirely different. None of his facial features resembled the face he had as a kid. And neither did his hair. To take some comparisons; At least adult Tiana looked the young Tiana. Young Rapunzel resembled adult Rapunzel, young Merida looked like adult Merida and young Hercules resembled adult Hercules. At least Tarzan had some different features as a kid opposed to adult, but at least he had the same hair which made the resemblance.
