Maybe either of those would catch your interest?

There's Matlal (unrelated to the Subeta one!), the leader of a group of aztec settlers arriving in Northern Scotland for an alternative history roleplay. You can have artistic licence with his outfit if you like, or just draw him in one of the existing ones. It also bears mentioning that he's muscular as heck so :D

And there's Nimue Jakande, black and blind contemporary hipster girl? :D Same deal as with Matlal - you can have artistic licence with her clothes, but you don't have to.

And if neither interests you then you don't have to force yourself.

Would you perhaps be interested in this OC? O:

If you're interested I have a few oc's! Here's Tobias and Zion

You have artistic freedom for their clothing, Zion wears Nike and Adidas usually, Tobias can be drawn in literally anything.

Thanks for the opportunity, I hope you get the practice you're after. ' u')7

Are you able to draw from a written description?
