Man I've totally heard of somethin similar to his back story but Idk where...
His backstory kind of reminds me of Rapunzel a little but that is just me .
Out of curiosity I have a question are you more used to with drawing European people or in a specific group of people ( I am really not trying to sound rude here )
The drawing of the African man do look pretty good 🏽
I kind of like the braids on the character or the cornrows (it looks like cornrows to me )
Since you have also mentioned that the world it is mostly European-styled , I think you should look at what did the Black people in that Continent looked like to have more of an Idea of the character.
I look at some but they are queens in England
