Give you an analysis? Please look at the picture. I chose this one because it's two common forms of cartoon characters, teenagers and young people, and it's better to put them together.

Teenagers' eyes are bigger than those of adults, but they still look smaller and narrower than those of girls, so they can't be painted as big eyes as girls, which obviously doesn't match the gender. Second, because of their own temperament, men are more suitable for painting eyelids and are more handsome. The drooping canthus is obviously a little uncomfortable or a girl's delicate and touching temperament. As long as you pay attention to these two points, they are basically the same, and you should also pay attention to your eyebrows. Men's eyebrows are thicker than girls', which makes them more imposing. ?

The same is true for young men. Young men's eyes are very distinctive, a little classical and more heroic. As long as you lengthen and shrink your eyes, they will become bigger. It should be noted that young men's faces must be drawn very long. Because it's an adult face.

It's basically the content above. I hope I can help you.
