I need help creating a character like this
I need help creating characters similar to this. I play a tabletop rpg with my friends for fun, it's nothing big. When a character appeared I would simply take a random photo from Google and say "that's what he looks like". But this character ended up becoming more important in the game and I wanted to create some images of him to use in the story, but as he is not a famous character I am having difficulties. Any help is appreciated!
