The correct answer to this open question is the following.
Having an understanding of imagery, proportion, balance, and design, help you to evaluate the validity of artwork in that those elements can help you to determine and appreciate the artistic value of the artwork the first time you see it. With these elements, you can realize the effort, dedication, skills, and abilities that the author put in the piece of art.
This is evident when you see the great pieces of work of Renaissance artists such as Michel Angelo in sculptures, or Leonardo Da Vinci in his paintings.
