It's pretty hard for me to do so.
I'm half Mexican, so that's how I look for the most part (although I can pass off as some kind of Arab-speaking person if I grow out a beard, but not Redguard). Not really a Mexican-looking race. It's to be expected, the games are modeled closely to Europe.
For the human races:
Bretons: Celtic, English, and French people (anybody from Brittany in France?)
Nord: Germanic peoples (specifically Scandinavian)
Imperial: Italian people
Nothing that looks like me XD. It's fine though, I'd much rather play as an elf.
Not with the physical character, but I did realize a while back that my main Breton Templar healer and his backstory is a projection of what I would want to be IRL if magic was real. Bringing peeps back from the brink of death, helping to protect the innocent from bad guys, basically saving the world!
I am lizard-people IRL.
Yes, I tried to make my Redguard look like a elder scrolls version of me, but I don't self-insert, instead I role play him how I would've been if I grew up in Tamriel with his culture and all.
