A four-step guide to drawing a cartoon duck, from simple gray shapes to a colored character with a beak, feet, and wing

Prompt

Create a four-panel, square layout guide for drawing a simple cartoon duck.

1. Panel one displays a grayscale oval for the duck's body.
2. Panel two shows a grayscale smaller circle overlapping the front of the oval for the head.
3. In panel three, a grayscale beak is added to the head, and webbed feet are attached to the bottom of the body.
4. The final panel reveals the completed  duck with color now with two eyes on the head, and a wing outline on the body.
