Suppose you are sitting in an art class, and you have been instructed to draw from memory the scene you see from a window in your own bedroom. Although you cannot actually see the top of a tree through the bedroom window, you still draw the complete tree. The error you have committed is called:

You had to paint what u see

Explanation:

You dont see the top of the tree so drawing the top of the tree is not what you can see
