In this winter scene, the sky is filled with delicate snowflakes drifting down from above. They look like intricate pieces of ice, with crystallized edges and light grey shadows from the sky that give them a more three-dimensional look. How to best color them is up to you, though for a more realistic feel I'd suggest using light shades of blue, grey and white to bring out the delicate details of the snowflakes. You can also use glittery shades of silver and blue to give them even more sparkle. Use some white snowflakes with no shading to designate that they are the highest in the sky and the lightest in color. With a little practice you can bring these dancing flakes to life as they drift in the air!
