Oh, sorry, this is a man, not a woman. He is more like Orlando Bloom in Pirates of the Caribbeans. I see that he is a man now. The hair and the nose made me think of a girl at first but his eyes and body is definitely a man of steel, not to be confused with a super man. I'm a fan of medicine. I like drawing, too. But this is not a knight? Maybe, he is a general.
He is not human originally. In the Middle Ages he was just a child. But in some alternative universes where he used to be human, he was a witcher(like in The Witcher universe) and the teutonic knight. But he's more of a healer, than a warrior. And this particular painting is just a picture, no story behind it yet.
Reminds me of the show, Rick And Morty.
haha, maybe. this AU stuff is very common among artists like me and young writers ^^ also I like R&M <3
