The center of the page features a curious scuba diver wearing a full wetsuit, flippers, and a diving mask. You can see the oxygen tank on their back and the regulator in their mouth, with small bubbles floating toward the surface. In their hands, the diver holds a camera and a flashlight to see into the deep corners of the reef.

Nearby, a friendly sea turtle swims by, and an octopus peeks out from behind the coral reefs. Look closely to find clownfish and angelfish darting between sea anemones and seaweed. The bottom of the ocean is covered in various sea sponges, adding lots of texture and detail to the entire environment.

Since this is an underwater scene, you might want to use different shades of blue and teal for the water. You can make the coral reefs look vibrant by using bright pinks, oranges, and yellows. The sea turtle often looks great in shades of olive green or brown, while the octopus could be a fun purple or even a camouflaging orange.

For the scuba diver, try a bold color for the wetsuit, like neon yellow or deep black, to make them stand out against the blue background. Using a silver or light grey crayon for the oxygen tank and camera gives them a metallic look. Don't forget to leave the bubbles a very light blue or even white to show they are filled with air.
