Planet Practice

Just needed to practice a few skills in Illustrator, specifically using masks and/or coloring shapes within shapes.  I had a project coming up where I knew I'd be doing quite a bit of this and didn't want to look like an idiot.  So I took 15 minutes to create this planet graphic.  I realized that after that what I really needed was to learn to make better "star field" backgrounds.  Another lesson for another time.
