This article talks about an important reference book for video game design, Drawing Basics and Video Game Art. It explains that video game art and ascetics is an evolution of art made in the Renaissance by famous artists like Michelangelo and Tintoretto. There are fundamentals of tangible artwork that can be incorporated into video game artwork, such as a sense of gravity, motion, color, and range of motion. The best way to learn these skills is to copy art from artists that inspire you. Sketching in simplified forms help to master a specific technique that you can focus on and improve. This technique was not only used by Renaissance artists, it's still an important technique used in modern video game design.
I can easily incorporate these concepts into my character art. I can practice artwork by copying characters from other video games like Legend of Zelda and Ratchet and Clank. I actually taught myself a lot about drawing using Sonic the Hedgehog as a character model. I normally draw every day and will try to recreate a lot of different characters that I see in video games.
