This is a great example of proportion and how it can create depth in a piece. Even though his entire piece is flat, the way that he creates some things proportionally smaller (the things that are supposed to be further away) than others (the things that are supposed to be closer) creates and extreme sense of depth.

This is a good example of how scale and proportion can be used to create an interesting piece that would otherwise be uninteresting. The fact that this sculpture depicts a spoon an cherry much larger than their real life sizes draws interest to the piece. Though they are proportionally the same, their scale is much larger than usual.
