As you look at the page, you will find a massive whale swimming alongside a smaller one, both covered in ornate designs and swirls. Below them, the ocean floor is filled with textured seaweed and branching coral that provides a home for several small fish. A tiny starfish rests near the bottom, adding a small detail to the seafloor.

Delicate bubbles drift upward toward the surface, creating a sense of vertical movement in the water. Every corner of the image contains small details, from the patterns on the whales' fins to the tiny scales on the fish. The dense line work ensures that there is always something new to discover as you work your way through the scene.

Because the line work is quite dense, using fine-tipped markers or sharpened colored pencils will help you stay within the small patterns. You might try using shades of deep blue and teal for the ocean water to create a sense of depth. Choosing bright, contrasting colors like orange or pink for the coral and starfish will make the background elements pop against the blue water.

Blending different shades of grey or blue on the whales can give them a sense of volume and make their ornate patterns look three-dimensional. For a special effect, you could leave the bubbles uncolored or use a very light silver or pale blue to make them appear translucent. Taking your time with the smaller fish will add a nice variety of color to the middle of the page.
