In this portrait, you will find a happy dog looking right at you. The most striking features are the large, round eyes and the sweet smile on its face. The dog has floppy ears that frame its head and a dark, shiny nose that sits right above its cheerful mouth.

Moving down, you can see the sturdy collar around its neck, which is a great place to add a pop of bright color. The dog's coat is decorated with several distinct spots, giving you the chance to experiment with different patterns. The clean, moderate line density ensures that the focal points, like the eyes and face, remain the star of the show.

Since this is a cartoon dog, you can use traditional colors like brown, tan, or black for the spots, or go wild with imaginative shades. Using a light cream or tan for the base of the fur helps the darker spots stand out. For the eyes, a touch of deep brown or even a bright blue can give the dog a lot of character.

The collar is a perfect opportunity to use a vibrant primary color like red, blue, or green. You might even want to use a metallic gel pen for the buckle if you have one. If you want to add some depth, try light shading around the ears and under the chin to make the dog's face look more three-dimensional.
