It’s usually not necessary to add every single detail of a subject to create a convincing drawing. But there are a few helpful rules to remember. For instance, you can make the details nearest the viewer appear closer by drawing them with sharper, darker lines. And progressively lightening lines helps create the feeling that an object is moving farther away from the viewer. Ultimately, though, the number of details you choose to add or leave out is irrevocably interwoven with your own artistic ideals.
