In order to create a character in Illustrator, you will first need to create a basic shape. You can start with a simple rectangle, or you can use a more complex shape, such as an ellipse or a star.
Once you have created your basic shape, you will need to add some basic elements to it.
First, you will need to add a layer mask to your shape. This will allow you to selectively edit the color of the shape. Next, you will need to add some basic details, such as eyes, a mouth, and a nose. You can also add text or other elements, such as clothes or accessories.
Finally, you will need to save your character as a .AI file.
