Everybody's an art critic...
Here at the university, we have had a number of art-related "incidents". One lad had produced a number of welded-steel hemispheres about 2' wide and 1' tall. These were left on the lawn in front of the art school where they were slowly rusting into oblivion. An intoxicated person got off the bus at the nearby stop, walked by the "sculptures", (according to a witness) and suddenly jumped on top of one, flattening it. Apparently satisfied, he continued on his journey.
In another case, I contacted a student who maintained that his sculpture had been vandalized. We went to the scene, which also happened to be a storage area for the sculpture department, piled with wood, metal, junk, and other materials. The student pointed at a pile of junk. "There!" he said. "Where?" I asked. "There, there...See..." he said, pointing at a pile of welded-up pieces of junk. "Uh...."
Seems another student had mistaken the lad's sculpture for a....Pile of junk, and merely appropriated some of it for his own pile. They worked it out.
As to the painting in question, I offer my opinion as a sometimes artist:
Absolutely dreadful.
