Looking closely at the page, you will notice the grumpy cat is the star of the show. His large eyes have heavy lids that clearly show his annoyance, and his small frown makes his expression unmistakable. He is sitting right in the center of a sturdy cardboard box with the flaps folded down.

The lines are clean and bold, making it easy to see where the cat ends and his box begins. You can see the texture of his fur and the simple details of the box construction. The background is kept clear so that all the attention remains on the funny interaction between the cat and his tiny cardboard home. It is a simple yet effective scene that captures a classic feline behavior.

For the grumpy cat, you might choose classic grumpy colors like dusty grays or deep browns. Using a lighter shade for his belly and face can make his features pop against the rest of his fur. The cardboard box looks best with varying shades of tan and kraft paper brown.

You can add some depth by using a darker brown in the corners where the cat sits to create a shadow. If you want to make the scene more vibrant, consider giving the cat bright, glowing eyes in yellow or green to emphasize his mood. Using colored pencils can help you blend different shades of brown on the box to make it look like real recycled paper.
