When you’re ready, try to use anime eyes to express emotion.
Things to note: Eye Styles: This varies greatly, not just between manga, but also between characters in the same series. Eyes are a very expressive feature in Manga, and a character’s eyes can tell you all about them. Proportions: Manga style is all about manipulating proportions, your character may be anywhere from three to eight/nine heads tall. Compare to a normal human figure, which is generally six or seven.
Head: Indicate which way it’s facing with a line, and then add the chin and cheekbones. Remember that the chin may be very pointy depending on your style. Shorter cheek and round chin indicates cuteness. Chest/Torso: Block it in with a circle, or a simple prism - more rectangular for guys, more triangular for girls. Make sure that with girls, the waist is thin, flaring out into rounded hips; while for guys, the shoulders are much wider, and the hips are narrow. Hips: Can be indicated with a sphere/circle. Limbs: Should be blocked in with ovals or cylinders, with circles/spheres for the joints. Hands and feet: Can be left simple for now, though you might want to indicate their positions.
