The central focus is a large, happy capybara moving through the water with its paws positioned for paddling. Above the animal, the water surface is visible with gentle ripples and light rays filtering down. Small, friendly fish swim in a school nearby, adding a sense of movement to the quiet scene.

At the bottom, you will find textured rocks and clusters of coral that provide a home for the local marine life. Long strands of seaweed sway back and forth in the underwater current, while tiny bubbles float upward from the plants and animals toward the top of the page.

Since capybaras have thick, coarse fur, you can use short, flicking strokes with a brown or tan colored pencil to create a realistic furry texture. For the water, try layering different shades of blue and teal, keeping the area near the surface a lighter shade than the deep bottom.

The coral and seaweed are great opportunities to use bright pinks, oranges, and deep greens to make the scene stand out. You might even use a silver or light blue marker for the bubbles to give them a shimmering, watery effect that looks like they are moving through the river.
