Use the white of the page as your snow! This technique, called negative space, makes the scene feel bright and clean without any extra work.
Color the panda's patches with a classic black. This strong contrast will make your adorable character pop against the white snow.
Give your panda a little personality by adding a colorful scarf. A bright red or a festive green would look wonderful and add a cheerful touch to the scene.
To give the snow some dimension, use a very light blue colored pencil to gently shade the areas around the panda's feet and under the snowflakes. This creates a subtle, realistic shadow effect.
