Let’s suppose I create this piece of art and it appears in an art exhibition.

Let’s further suppose that you attend this exhibition and someone asks your opinion of this particular work. Your reaction to it is visceral (positive or negative) but difficult to put into words. Friends and relations, I have the answer for you. Go to The Instant Art Critique Phrase Generator at Pixmaven.com, enter any five digit number in the box and a critique will appear. Here are some examples of what you might get:
“With regard to the issue of content, the disjunctive perturbation of the negative space seems very disturbing in light of the eloquence of these pieces. ”
“As an advocate of the Big Mac Aesthetic, I feel that the metaphorical resonance of the figurative-narrative line-space matrix spatially undermines the exploration of montage elements. ”
Memorize a couple of these so you will be ready. If ever called on to use them though, be sure to confidently announce them in a clear voice and then keep moving. Take no questions and don’t turn your back on the artist.
