Draw 12 images of marbles and a few other small components.
See attached pictures.
The backgrounds should be white, disregard the green rug underneath each image.
Also the picture of the rug on the floor can be a solid color no need to include the rug details.
To make things easier (also preferred) the marbles of the same type can be the same image just different colored. There are two marble types solid colored and striped (see images).
