Supermoon - Watercolor Painting

Last night, I was thinking of a subject that needed only 2 colors, black and white. Then, I came up to this Supermoon watercolor painting.

_{Supermoon (4th Painting Attempt)}

A supermoon occurs when the Moon's orbit is closest (perigee) to Earth at the same time the Moon is full. So what's so special about a supermoon? For the interested observer, there's plenty to see and learn. The Moon orbits Earth in an ellipse, an oval that brings it closer to and farther from Earth as it goes around. ^source
