Avoiding Monotony en route

Ed Whitney used to caution students to "avoid monotony en route." 

So, you have a line.  It goes from point A to point B.  It's a long line.  Mr. Whitney would insist that you give us a break along the way by interrupting that line. 

So, you have a shape.  If it's a rectangle, try getting something to pop up from it, or overlap it with another shape to interrupt the first shape..

So you have line of trees.  Avoid the monotony by changing the color and the value en route.

In short, look for potential areas which could be monotonous and think of a way to make it more exciting and less monotonous. by changing color, texture or value along the way.  And definitely look for uninterrupted lines that need to be broken.
