One thing that makes cartoon people drawings easy is avoiding too much detail. Keeping the features basic and exaggerating certain aspects, like big eyes or a big smile, can make it simpler. Also, having a consistent style throughout helps.
The main difference is usually in the style. Horse cartoons might focus more on character expressions and cuteness, while comic strips might have a stronger storyline and more complex panel arrangements.
A pie eyed cartoon is appealing because the exaggerated eye size creates a sense of expressiveness. It allows the characters to convey emotions more vividly. Also, the simplicity of the style can be visually appealing and easy to remember.
Maybe some mythological or fantasy cartoons. In such cartoons, old men might be depicted as having a divine spirit, like in stories related to ancient gods and their wisdom.
