I saw that post, but things like height are irrelevant, because we indeed don't know what his age is. We need to look at their heads, and their basic facial features look pretty much the same to me, just younger, this new Link even has the exact same hear-style!
Hight is absolutely not irrelevant. If you're taller, you're probably older. If you're shorter, you're probably younger. It doesn't matter if we don't explicitely know his age. Anyone with eyes should be able to tell that he's younger. This isn't rocket science. His face looks younger. His eye's are bigger, more lively, and shaped completely different from SS and TP Link. SS and TP Link have eyes shaped exactly the same to each other, down to the last pixel. His eyebrows are much thinner than SS, TP, or really any Link to date. SS and TP Links' eyebrows are much thicker. His hair is completely different. It looks absolutely nothing like SS or TP Link's hair. His "sideburns," for lack of a better word, are way longer than SS, TP, or literally any 3D incarnation of Link thus far. It looks like ALBW Links hair, with a ponytail.
This Link looks absolutely nothing like TP or SS Link, aside from having brown hair, being a male, and having pointy ears.
Well, this is new.
