At the top of the scene, a large hammerhead shark glides through the water, surrounded by tiny bubbles rising to the surface. Beside him, a gentle sea turtle swims calmly along. The ocean floor is packed with detail, including a happy crab positioned near a textured seashell. You can spot a delicate starfish resting on the sand and several small fish darting between the plants. The background is filled with various types of coral and a wavy sea anemone, providing a home for all these different creatures. Each element offers a chance to experiment with different textures and patterns found in nature.

For the hammerhead shark, try using a soft gray or even a light blue to make him stand out against the water. The sea turtle looks great with different shades of green on its shell, perhaps alternating between light and dark for each segment. The coral reef is where you can really use a variety of bright colors like pink, orange, and purple. Using a light blue crayon or colored pencil for the water background will help make the colorful fish and the orange crab pop off the page. If you want to add a special touch, use a silver or light blue metallic pen for the bubbles to give them a shiny, watery look. Layering colors on the coral can also create a nice sense of depth.
