10 Mind Blowing Optical Illustions

Perspective is something many artists struggle with especially when adding structures to their drawings or paintings.  It creates depth in our work.  As you look at landscape you see that things get smaller, color less intense and details blur as they get farther away from you.  That's were perspective drawing comes in whether you are drawing roads, bridges, structures and even a bicycle's wheels.
