In the center of the page, the octopus stretches out its long arms, carefully clutching a spiral seashell. Its large, friendly eyes and wide smile are the main focal points of the artwork. Perched nearby is a small, curious crab with tiny claws and a happy expression, looking up at its larger friend.

Surrounding our main characters, several stalks of seaweed grow upward from the bumpy ocean floor, adding texture and height to the composition. Throughout the water, various sizes of bubbles float toward the surface, creating a sense of movement. The background is open enough to allow for a beautiful custom-colored water gradient or additional sea details you might want to add yourself.

Since this is a cartoon scene, you can use any colors you like. Many people enjoy coloring an octopus in shades of bright purple, orange, or even a soft pink. For the crab, a classic vibrant red or deep orange will make it stand out against the blue water.

The seaweed looks natural in various shades of green, while the seashell can be a mix of creamy yellows and soft browns. To make the bubbles look realistic, try leaving a tiny bit of the white paper showing and using a very light sky blue around the edges. A light sandy tan works perfectly for the bottom of the sea to give it a warm, beachy feel.
