I supervise beginners at our art school, and most often they make the same mistake - they mix styles or choose the wrong one. In order not to repeat the same thing to everyone, I began to recommend them to read one article character art styles click here. It really explains everything: from the difference between cartoon and realistic styles to how to choose an approach based on the genre of the game. After reading, beginners better understand the task and make an informed choice. The article saves me hours of explanations and raises the overall level of the group.

This is an excellent basic material to start learning with.
