Step 12 - To create the environment, begin making little elements such as grass, plants and stones. Draw several grass shapes and fill them with different gradients, using transparency to make them look as though they’re shrouded in fog. Copy groups of grass to save time. Fill in the background with similar elements, making distant layers lighter.
Step 13 - The next step is adding a light source. In tundra, the light is pale and scattered. So make a simple circle and fill it with Light Radial gradient. Make the outer colour of the gradient fully transparent. Adjust the gradient sliders to give softness to the sun’s shape. Use this technique to make small particles and distribute them over the picture.
Step 14 - If you want to add some other creatures such as deer in the background, find some pictures of them, and outline their shape and place them in the background.
