Composition refers to the organization, arrangement, and combination of objects within the borders of a drawing space. For a great drawing, you want to bring the eyes of the viewer toward your center of interest within an aesthetically pleasing composition.
The idea that clockwise motion represents the forward motion of time so powerful that it's hard to look at such a watch or clock without having the slightly unsettling feeling that time is running backwards.
The Earth rotates (spins) counter-clockwise as viewed from above the North Pole, which is also from above the ecliptic plane of the solar system. This is the arbitrary up and down convention that allows us to say which direction the Earth is spinning. Most other objects in the solar system spin and orbit counter-clockwise as well. Depending on your location on the planet, the Earth's spin (west to east) could be seen as clockwise or counter-clockwise. In the Northern Hemisphere, looking south toward the equator, the Earth turns counter-clockwise.
