In the center of the page, a smiling mermaid sits comfortably on the broad back of a massive whale shark. The whale shark is covered in its signature spots, providing many small circles to color. Below them, you will find intricate clusters of coral and sea plants that frame the bottom of the image. Tiny bubbles float upward from the seabed, adding a touch of magic to the water.

In the background, rolling ocean waves indicate that they are swimming near the surface. The mermaid has long, flowing hair and a detailed tail that overlaps with the whale shark's skin. The whale shark's large fin and wide mouth give it a friendly, cartoonish appearance that makes the whole scene feel welcoming and fun for artists of all ages.

For the whale shark, you might want to use a dark blue or gray for the main body, while leaving the spots white or choosing a bright contrasting color like yellow. The mermaid offers a great chance to use your favorite vibrant shades for her tail and hair. Shimmering greens or purples look fantastic on scales.

When working on the coral at the bottom, try using a variety of warm colors like pink, orange, and red to make it pop against the cooler tones of the water. You can create a sense of depth by using a lighter blue for the water near the top where the waves are and a slightly darker blue as you move toward the bottom. Use a very light blue or even a silver metallic pen for the bubbles to give them a shiny, realistic look.
