we need diverse books
One of the problems with drawing diverse characters in cartoons and comics is that making main characters generic is one way to get readers to identify with them. We read characters into even the simplest shapes.
In the books I read as a child, there was never anyone like me. There was no brown-skinned girl with dark brown hair and eyes. There was no brown-skinned girl who spoke to her relatives in another language. There was no brown-skinned girl who went to the temple on Sundays.
