Ozpin kinda doesn't count, since we have the theory that his Aura is so powerful that it stopped his aging and replinishes his body, thus preventing him from getting wrinkles and preventing his organs and skeleton from wearing out from age.

Buuuut...

There's Oobleck, who went to school long enough to get a doctorate, yet he looks like he's in his early 20s.

There's Glynda who looks fairly young, but could be in her 40s for all we know.

We have no idea how old Roman is.

So, yeah, it really is hard to tell how old a character is. It doesn't help that big round anime eyes, like the females of this show have, make them look younger and sometimes cuter.

Also, Raven's eyes are actually different from Yang's. They're a very similar shape, but still different. Really, the only part of her model that is a copy of Yang's is her hair because they ran out of time and couldn't make a hair model for her. The hair models have tons of polygons in them and have to be properly rigged, and they have to put collision boxes on them and make sure the boxes actually react properly. It was easier to just copy Yang's hair model and slap different textures on it for the time being.
