Building a Snowflake
This one started with a circle, and then some guidelines drawn in every sixty degrees so I could get a hexagon and build on that shape. Then I just thought about what forms lines and shapes seemed interesting and marked those with color. Then I erased the guidelines and started filling the interior. Some of the original shapes got broken down into smaller pieces to make them more interesting , and then, finally, the background was shaded in to finish it off.
