Onmyoji Doujin Drawing was a rather abstract concept because Onmyoji was a Japanese game, and the drawing styles were very different. However, we can discuss it from the following aspects: 1. composition and proportion: composition and proportion are the basics of painting. In the drawing of an Onmyoji, one had to pay attention to the arrangement and combination of the characters, as well as the coordination between the different elements. 2. Color and style: Color is one of the most important elements in painting. The color must match the character's personality and temperament as well as the atmosphere of the game background. The style had to match the overall atmosphere and characteristics of the game. For example, the style of Japanese games was often refreshing and elegant. 3. Details and performance: Details and performance are important skills in painting. Details must fully express the characteristics of the character and details must accurately express the emotions and state of the character. The background and atmosphere are one of the important elements of painting. The background must fully express the background and atmosphere of the game world. The performance must accurately express the environment and scene where the character is located. In the Onmyoji Doujinshi drawing lessons, it ultimately depended on one's drawing skills and aesthetic perspective. Everyone had their own unique painting style and techniques, so it was important to constantly practice and improve to explore their own painting style and characteristics.
