In the center of the page, a large cartoon crab stands happily on the sand. He has two big pincers and a wide, friendly smile. Scattered around his feet are several different types of seashells, each with unique shapes and patterns. A small starfish rests nearby, adding even more detail to the sandy ground.

Looking toward the background, you will find the rolling ocean waves reaching the edge of the beach. Above the water, a bright sun shines in the sky next to a few fluffy clouds. The moderate line density makes it easy to distinguish between the sand, the sea, and the sky, allowing for plenty of color variety throughout the whole illustration.

For the crab, bright shades of red or orange are classic choices, but a purple or blue crab could look magical too. You can use a light tan or pale yellow for the beach sand, perhaps adding tiny brown dots with a marker to represent grains of sand or small pebbles. The starfish looks great in vibrant yellow or pink to make it stand out against the beach.

To give the ocean waves depth, try using a dark blue for the deeper water and a lighter teal or aqua near the shore. The sun can be a brilliant gold, while the clouds can be left mostly uncolored with just a hint of light blue shading around the edges. Using colored pencils allows for soft blending in the sky, while markers make the crab's bold features really pop.
