That is proper human proportioning. As you can clearly see, PoR Ike has way too long of legs. It doesn't "look it to me", it IS.
Why does it have to be realistic? It doesn't. However people were claiming that the new design is way too skinny, but that's not true according to realistic proportions, just that the head is too big. My point was never that FE had to match up perfectly, but that it didn't.
Also, we can reasonably say that the artist's goal IS to match up correctly but that's neither here nor there.
I'm not too fond of the redesign, but I do agree that they are supposed to look different. However, it's reasonable to expect that their goal is to still capture the character in question. While the design, strictly speaking, is fine, the actual art isn't that great in terms of posture and positioning.
EDIT:
Far from? No not at all. It's stylized to be skinnier than normal, (and not even that much), but it matches pretty accurately with a young girl.

While not a girl, you can see that the torso is dramatically skinnier at a younger age. The height is about right, the head size isn't too off. Really the only "flaw" is the stylized skinniness.
