The head of a Manga character is by far the most important part! Why? Because the style is based around it. Everything after the head is more or less just another piece of a cartoon character, and by that I mean that for the most part, you can find everything else in other styles of cartooning and comic booking.
To begin your Manga character, first draw a circle. This will be the top of your character’s head and help shape all the later aspects of the head such as the eyes and mouth.
