Yeah so since beards & bangs have similar designs on similarly-built characters, I'd say the artist-sama doesn't draw many different styles much. The muscular old men with beards look like mirrors, & the lolis with bangs & bobs also look the same if not for their colouring & clothing styles. Just once I'd want to see a Bob-Ross-looking character, or a Rastafarian or even Qing Dynasty braids. I'm talking about just the hairstyles or facial hair here, not the race or culture. It ma be hard to draw but curly hair is a good exercise to extend your drawing style or technique.
