If you want to draw cartoon eyes, you must first understand the character you want to draw. Different personalities need to draw different eyes. For example, the bigger the black eyeball of the eye, the more gentle and clever the character will be, which is generally used to draw female characters. If the black eyeball is small, it will appear very deep and generally represent the male role. Also, when drawing eyes, the position and size of highlights and pupils will affect the personality and appearance of the whole character.
The most important thing to draw cartoon eyes is to observe the eyes first, such as where the pupils and light can be cute, charming and handsome, and happy and sad. All the good things need to be discovered in our life. You don't have to be very skilled to draw cartoon eyes, but the basic work of drawing must be solid, and then you should find materials from life and adopt different painting styles for different characters.
Secondly, I think it is necessary to be proficient in painting and then accurately express the character with my eyes. For example, in the anime "Douluo Mainland", the eyes of male characters such as Tang San and Oscar are slightly phoenix-eyed, which will be relatively flat and the black eyeballs will be relatively small. When characters speak or express their opinions, they will show the tenacity and profundity of male roles. For Xiao Wu, Zhu Qing, Ying Ying and other female characters, the eyes will be round in appearance, and the black eyeballs will be larger, showing the feeling of water, which is in line with the gentle and lovely characteristics of female characters. Among the female characters, Xiao Wu and Ying Ying are gentle and charming, but Zhu Qing is still relatively strong, so her eyes are not round.
The eyes are the windows to the soul. Whether it is an anime character or a real person, eyes are an important feature to express the character, so if you want to draw cartoon eyes, you should base yourself on life.
