As you look at this scene, the first thing you notice is the baby dinosaur standing right in the center. Its large, expressive eyes and happy mouth show just how friendly it is. Moving down its back, you will find a row of neat spikes on back and several spots on body scattered across its skin. The ground beneath its feet is filled with interesting details to color. There are various rocks of different shapes and sizes grouped together. You will also find small water puddles reflecting the sky and several prehistoric plants growing nearby. Every element works together to create a lively outdoor environment for the little dinosaur to roam.

You might want to start with a bright shade like lime green or sunny yellow for the dinosaur's body to make it look cheerful. Using a contrasting color for the spots on its body and the spikes on its back will help those details pop. For the water puddles, a light sky blue or a shimmering silver could look very realistic. The rocks can be colored with different shades of grey and brown to give them texture. If you want to add some extra depth, try using a slightly darker version of your main color to add shadows around the legs and under the belly. Soft strokes with colored pencils work well for the smooth skin, while crayons can add bold color to the surrounding plants.
