Oh
I just wrote the backstory for one of my characters and she a part of it so I was like what if I made her a b r i t i s h w h o l e s o m e b e a n.
For my inspiration, she's inspired by British culture and Elizabethan Era England, which I'm learning about in my European history class lol. Honestly, a lot of my inspirations come from history, which is probably why they are all royal medieval-ish characters.
idk about you but I personally often get inspiration from reading or from characters I like.
So maybe try to think of some character or historical figure you admire, idk.
Or the easiest way to make an oc is to implement them in another one's backstory, as you did with Cherry and Jace.
