This final entry in the Principles of Design series is all about "Unity", which is the state of balance in your image.   Think of your illustration as a sauce -- you don't want any individual ingredient to stand out too strongly.   Likewise,  no single principle of design should stand out above another, they should all combine into a pleasant mixture.  This is called "unity".  If you missed any of the previous entries in this series, make sure to check out the Principles of Design Series!
