So, why isn't this a thing yet?

Here's what I think SE should do:
-Add more facial features like larger eyes, rounder jawlines, bigger ears for Miqo'te, smaller horns for Au'Ra, etc., so players can have a more youthful/baby-faced look without being actual children. More character customization is always a plus and I'm surprise SE hasn't add more facial features since launch.
-Add a more youthful looking race. Heal showed a good example with that Viera concept art. So long as they don't get a hyper-sexualized and/or deformed as the Elin in Tera Online...Because that's creepy.

I think this would be a good middle ground. Add some younger and older looking facial features and the options for slightly more youthful and older "builds". Not necessarily children, or elderly, but a little younger and older than what we have.

I would also probably change my race to that Viera-esque race if they ever implemented it. Those are really cute and classy looking.

More age variety among PCs and NPCs would be really cool to see, I think.
