No worries lol. I like hearing about people's inspirations, and I ramble and write so many different people of different ethnicities too.
Essence is African-american of Sudanese descent, her little sister is biracial white American on her father's side, who I think is probably of Dutch and English descent. Essence's ML, Dominic, is Vietnamese, first gen American.
It seems like a very large portion of your OCs are multi-ethnic as well lol, which you probably have more of them than me, though I have quite a lot of multi-ethnic or biracial OCs as well.
Here is a reference of Essence + a bit more detail because my art is not good enough to make everything as clear as I'd like it to be rn lol:

Essence is 5'10, very thin (would probably be like a size 2 ) without nearly anything in the way of curves. She has long legs though, which, along with her hair, are the two traits she's proudest of lol.
And (though you can't tell from the picture) her complexion is canonically nearly literally black. (inspired by Nyakim Gatwech)
She has very sharply slanted, always slightly sleepy eyes. I have no idea why her eyes are slanted, because no one else in her family has them. At least as far as she knows.
I was thinking of long distance runners, and also celebs like Zendaya and Taylor Swift with her build lol. But the eyes still have no point of reference, I don't know where they come in.
there, now i've rambled and we're even lol
