This is so cool! Well, I have a character named Yoon who is the best friend of my main character in my book. He's a very talented pitcher for the baseball team, and is expected to accomplish great things. Since he's a sports player, Yoon is six feet tall and has a muscular/skinny built. When it comes to his personality, he has no filter and does not talk or say many words unless necessary. He also rarely smiles. The only times he does, is when he is truly happy. By the way, all my characters are Korean since my story takes place in Korea!
So basically:
- broad shoulders
- semi tanned skin (medium skin tone in foundation, if you know what that color is, will do!)
- dark hair under a blue baseball cap.
- neutral expression.
- he's quite the good-looking character as well, if that helps hahaha
EDIT: Your drawings are so good might I add I like the artistic style that you have.
