The faces we get to choose from are all quite young-looking. All I ask for is at least 1 old looking face for each race/gender combination, and grey-ish hair color to match. It would be a shame to have all these character creation possibilities yet unable to role-play an old man.

Aye, I want grizzled. 

I would also like some fat body-type options!

Do you think they will add some Forton-like portraits? People seem to love his hair:

Looking at the character portraits available I'm pretty sure they will add more later on.

 

But while we're at it: More diversity would be good in general. It's not just age. There just isn't a portrait fitting the Ocean Human character, that I created as my first character.

That being said, I still think there are more to come.

Yes for older men and women types and portraits and for more body types. Playing an old and experienced character can be a great deal of fun. I've chosen a silver haired gent for Divinity: OS a few times.
